### Quantum computers: Eight ways quantum computing is going to change the world

Quantum computers have been generating significant attention from the world’s biggest companies and governments. While they are still in the early stages of development, these computers have the potential to revolutionize computing by removing the constraints of complex problem-solving. This article explores eight potential use cases for quantum computing that could bring about significant changes in various industries.

One area where quantum computing could have a profound impact is in drug discovery. The process of finding new drugs involves complex molecular simulations, which require massive amounts of calculation. Quantum computers have the ability to carry out numerous calculations simultaneously, making them well-suited for simulating the intricate interactions between particles in molecules. This could drastically speed up the process of identifying potential candidates for drugs, leading to faster and more cost-efficient development.

The field of battery design also stands to benefit from quantum computing. To improve battery performance, scientists need to model the behavior of molecules that could be used as battery materials. Quantum computers excel at handling these data-heavy simulations, allowing for more accurate predictions and the development of better-performing batteries. Companies like Daimler are already exploring the potential of quantum computing in designing lithium-sulfur batteries.

Quantum computing could also revolutionize weather prediction. Current weather forecasts often lack precision due to the limitations of classical computers in processing vast amounts of data. Quantum computers, with their ability to analyze numerous environmental factors simultaneously, could provide significantly more accurate predictions. Partnerships like the one between the European Centre for Medium-Range Weather Forecasts and Atos’s quantum computing simulator are already exploring the impact of quantum computing on weather and climate prediction.

In the financial sector, quantum computing could enhance the efficiency of banking operations. Specifically, the application of quantum computing to Monte Carlo simulation could speed up financial asset pricing and market prediction. Quantum computers’ computation abilities could accelerate Monte Carlo calculations by up to 1,000 times, offering significant advantages to banks. Goldman Sachs, for example, has been researching the potential of quantum computing in this area and anticipates running Monte Carlo simulations on quantum hardware within the next five years.

The field of natural language processing (NLP) could also benefit from quantum computing. Classical computers struggle to understand the nuances of language due to its interactive and contextual nature. Quantum computers may offer a more intuitive way of representing and processing language by leveraging their network-based approach. Quantum natural language processing (QNLP) is an active area of research, with companies like Cambridge Quantum Computing developing tools and software for QNLP.

The traveling salesman problem, a common optimization challenge faced by companies managing complex supply chains, could be efficiently tackled using quantum computing. Classical computers struggle to handle the vast number of possible routes, leading to simplifications and approximations. Quantum computers’ ability to evaluate multiple routes simultaneously could provide optimal solutions much faster. ExxonMobil, for instance, has partnered with IBM to optimize shipping routes using quantum algorithms.

Traffic congestion is another problem that quantum computing could help address. Optimizing traffic signals in cities requires considering multiple variables and possibilities, which becomes increasingly complex for classical computers. Quantum computers, however, can assess different scenarios simultaneously, leading to faster and more efficient solutions. Microsoft, together with Toyota Tsusho and quantum computing startup Jij, is working on developing quantum-inspired algorithms to reduce congestion in simulated city environments.

Finally, quantum computing has the potential to enhance data security. Classical security algorithms rely on deterministic processes, making them vulnerable to powerful computers that can predict encryption keys. Quantum randomness can be harnessed to generate encryption keys that are virtually impossible to reverse-engineer. Startups like Nu Quantum are already working on generating random numbers using quantum computing to strengthen cryptography keys.

In conclusion, quantum computing holds immense potential to transform various industries. From drug discovery and battery design to weather prediction and traffic optimization, the capabilities of quantum computers could revolutionize how we approach complex problems. While quantum computing is still in its early stages, ongoing research and partnerships indicate that the world is actively exploring and investing in its potential applications.

### What more can a Quantum computer do than a normal computer?

Quantum computing is a fascinating concept that can be understood using an analogy of a shell game. Imagine a game where you have 1,000 shells, each representing a qubit in a quantum computer. In this game, a magician waves a wand and randomly places either a pea or a cashew inside each shell. Additionally, each shell has four colored numbers written inside: red, green, black, and white, all equal to 1/2.

The objective of the game is to perform a series of moves without ever looking inside the shells, and ultimately open them to find the desired answer. The moves you can make as a quantum programmer are limited to three actions.

The first move is called the double tap move. You tap one shell with your left hand and another with your right hand. If the left-hand shell contains a pea, the right-hand shell will flip to a cashew, and vice versa. This move allows you to change the contents of the shells without observing them directly.

The second move is the color number swap. You select a shell and choose either the pair of colored numbers {R, G} or {B, W}. You replace the chosen pair with new values, but this move doesn’t require any further operations since the probabilities remain unaffected.

The third move is the probability fiddle. Once again, you point to a shell, and the magician waves the wand to update the colored numbers. Then, the pea or cashew inside the shell is replaced with a new probability value. This move, and only this move, requires the use of quantum systems.

The game continues until you decide to open all the shells. If you fail to find the correct answer within a predetermined number of attempts, the house (quantum) wins. However, if you succeed in obtaining the desired answer, you win. Remarkably, there are certain math problems for which we have proofs that assure you can solve them with very high probability, making it a game where you are almost guaranteed to beat the house.

While the rules of the game are simple, there is a lot happening beneath the surface. For instance, executing the probability fiddle move 1,000 times can generate a vast number of different outcome lists. The computational power required to list and optimize all the possible combinations of peas and cashews, even with just 360 moves, would far exceed the capacity of classical computers.

This is where quantum computers shine. They can optimize over lists that are practically impossible to describe or process using classical methods. The sheer magnitude of possibilities that quantum computers can handle is mind-boggling. It exceeds the capabilities of classical computers by an astronomical margin, raising philosophical questions and exciting possibilities.

In conclusion, the described shell game provides an analogy for understanding the basic principles of quantum computing. It involves manipulating the contents of qubits through a limited set of moves, all while never directly observing their states. Quantum computing opens up a realm of computing power that surpasses classical limitations and offers new avenues for solving complex problems.

### Why and how is a quantum computer faster than a regular computer?

A quantum computer is believed to be faster than a regular computer due to its ability to take advantage of quantum phenomena. In theory, quantum computers work by using qubits, which can exist in multiple states simultaneously. These qubits are manipulated to find a stable configuration that satisfies the desired criteria, similar to the way salt particles arrange themselves in a pattern when exposed to a specific sound wavelength. This allows quantum computers to potentially calculate answers instantly, unlike classical computers that would require emulating each particle individually. However, the practicality of quantum computers is uncertain.

One of the challenges with quantum computers is the inability to communicate directly with quantum bits or qubits. Superposition, which refers to the ability of a qubit to be in multiple states simultaneously, is still a theoretical concept that attempts to explain uncertain data. It suggests that until a specific equation is solved, the qubit can be considered to have all possible values, which then collapses into a single value. However, this is more of a way to work with incomplete information rather than a representation of reality. If someone already knows the value of a variable, the uncertainty lies only with those who lack that information, and the variable itself has a definite value.

Quantum entanglement is another concept related to quantum computers. According to mainstream theory, when one entangled particle is observed, instant information about the other particle is gained. Although this may seem like magic, it can be compared to a pair of gloves. If two gloves are placed in separate bags and taken to opposite ends of the galaxy, when one person discovers they have the left glove, they know the other person has the right glove. There is no physical communication involved; both individuals simply possess the knowledge once they check their respective bags. The idea of a wave function collapsing upon observation is a way to conceptualize this phenomenon, but it is not an accurate representation of how things actually work.

The concept of superposition, where something can exist in multiple states simultaneously, challenges common sense. It traces back to the Copenhagen Interpretation, which has sparked considerable debate. There is hope for a better explanation that goes beyond the probability-based approach. Even Schrödinger himself disagreed with the notion and used the example of the famous Schrödinger’s cat thought experiment to highlight the contradiction of a cat being both dead and alive. Nevertheless, multiple values for the same entity at the same time were accepted, going against the purpose of variables—to provide precise meaning—and the principles of proving or disproving theorems.

Despite the belief that quantum computers hold promise, there is skepticism regarding their practicality and reliability. Quantum computers are highly specific to particular problems, requiring rewiring for each new calculation. Furthermore, their stability is a significant concern. Comparatively, it is akin to calculating the ratio of two numbers by cutting a plane to the appropriate size, sprinkling salt on it, and playing music to generate patterns.

In summary, quantum computers are thought to be faster due to their ability to leverage quantum phenomena. They operate on the principles of superposition and quantum entanglement, which allow for multiple states and instant information transfer. However, the practicality and reliability of quantum computers remain uncertain. There are challenges in communicating with quantum bits and concerns about the stability and specificity of quantum computations. Despite significant investments and expectations, it is possible that quantum computers may not deliver consistent and reliable results.

### IT Explained – Quantum Computing Explained

Quantum computing operates at the quantum level, utilizing atomic-level bits known as qubits. Unlike classical computers, quantum computers possess significantly greater power and efficiency, and can even tackle tasks that are impossible for traditional computers to accomplish.

Quantum mechanics governs the operations of quantum computers, functioning on a much smaller scale where things behave differently compared to the macroscopic world. This unique behavior of qubits distinguishes them from regular computer bits. While a classical bit can only hold a value of ‘1’ or ‘0’, a qubit exhibits uncertain values. It can be envisioned as a spinning coin, simultaneously representing both heads and tails or any intermediate state—a characteristic referred to as superposition.

The concept of superposition allows qubits to execute multiple tasks concurrently, granting them immense computational capabilities. For instance, a classical computer would need to explore each possible path one by one in a game of chess. Conversely, a quantum computer can explore all potential paths simultaneously, resulting in exponentially faster and more efficient computation.

There are currently two classifications of quantum computers, defined by their computing power. The first category is Quantum Advantage, wherein the quantum computer performs tasks that are feasible for classical computers, but at a much greater speed—hundreds or even thousands of times faster—and with enhanced power. The second classification, known as Quantum Supremacy, refers to quantum computers accomplishing tasks that are beyond the reach of classical computers.

The potential applications of quantum computing are extensive, spanning various industries. For instance, it holds promise in simulating weather patterns more accurately, facilitating precise forecasts. Real-time fraud detection with zero errors and the decryption of highly complex cryptographic algorithms are also areas where quantum computing could have a profound impact.

Nevertheless, despite the active development of this technology, many questions remain regarding its full potential and the extent of its capabilities once it reaches maturity. Humanity still lacks a definitive timeline for extensive utilization of quantum computing, leaving both possibilities and uncertainties open.

### Why can a quantum computer perform certain computational tasks more efficiently than a conventional computer?

Quantum computers have the potential to perform certain computational tasks more efficiently than conventional computers. While our understanding of quantum computing is still limited, there are fundamental differences between quantum and classical systems that contribute to this increased computational power.

Classical computers are built based on classical physics, where quantum effects are often seen as noise or obstacles. To make computers more understandable, quantum effects are intentionally destroyed, and computations are based on the statistical behavior of particles. This simplification allows for the representation of information as binary bits (0s and 1s) and enables complex computations to be performed.

However, simulating the behavior of complex quantum systems using classical computers is incredibly challenging. The computational requirements for even small-scale simulations quickly become infeasible. This presents a problem because we have a mathematical model of nature that we believe to be accurate, but we lack the computational capabilities to simulate it effectively.

Fortunately, advancements in technology have allowed us to experimentally replicate simplified scenarios of quantum systems using specialized apparatus. By arranging these experiments and measuring the outcomes, we can obtain results that are computationally infeasible for classical computers to generate. In this sense, the apparatus becomes a quantum computer, capable of performing computations that were previously impossible.

It is important to note that the power of quantum computers lies in their ability to compute tasks that are of interest to us, rather than solely simulating quantum systems. For example, quantum computers have shown promise in solving complex problems such as factorizing large numbers, which has implications for cryptography.

So why can quantum computers achieve these feats that classical computers cannot? The key lies in understanding the inherent difficulty of simulating quantum systems using classical computation. Quantum computers operate using quantum bits, or qubits. Unlike classical bits, qubits can exist in superposition, representing a range of possible states rather than a definite 0 or 1. Measurement of a qubit reveals information about its state but also destroys that state in the process.

The behavior of qubits is inherently probabilistic and uncertain. It is impossible to ask questions like Does the state equal Singapore? Instead, we can ask questions about the proximity of the state to certain reference points and receive probabilistic answers. Measurement outcomes are deterministic, meaning that repeated measurements will yield the same result if the state remains unchanged.

The complexity increases when dealing with multiple qubits. Entanglement, a phenomenon unique to quantum systems, allows qubits to become correlated in ways that classical bits cannot. This entanglement necessitates a higher number of variables to represent the state of the system accurately. As the number of qubits increases, the computational requirements grow exponentially, making it challenging to simulate quantum systems effectively.

The nature of quantum systems and the behavior of qubits are still not fully understood. They defy classical intuition and operate according to the principles of quantum mechanics, which can appear strange and counterintuitive. Despite this, scientists aim to exploit these properties rather than fully comprehend why they work the way they do.

In conclusion, quantum computers can perform certain computational tasks more efficiently than classical computers by leveraging the unique properties of quantum systems. The ability to arrange experiments and measure outcomes provides a computational advantage over simulating these systems using classical computers. While quantum computing is still in its early stages, it holds the potential for groundbreaking advancements in solving complex problems that were previously beyond our reach.

### What is Quantum Computing? | IBM

Quantum computing is a revolutionary approach to computation that leverages the principles of quantum mechanics. Unlike classical computers that use bits to process information, quantum computers employ qubits, which are capable of existing in multiple states simultaneously. These qubits are implemented using superconductors, which operate at extremely low temperatures to prevent decoherence, a phenomenon that disrupts quantum states.

To achieve the necessary low temperatures, quantum processors rely on super-cooled superfluids. At these ultra-low temperatures, certain materials exhibit superconductivity, allowing electrons to move through them without resistance. This property enables the formation of Cooper pairs, which can carry charges across insulators through a process called quantum tunneling. Josephson junctions, created by placing two superconductors on either side of an insulator, serve as the superconducting qubits in IBM’s quantum computers.

Control over the behavior of qubits is crucial for performing computations. In IBM’s quantum computers, this control is achieved by directing microwave photons at the Josephson junctions. These photons manipulate and read out the quantum information held by individual qubits, enabling the execution of quantum algorithms.

One of the key features of quantum computing is superposition, which allows qubits to exist in a combination of all possible configurations simultaneously. While a single qubit may not be particularly useful, groups of qubits in superposition can create complex and multidimensional computational spaces. This property opens up new ways of representing and solving complex problems.

Quantum entanglement is another phenomenon essential to quantum computing. When two qubits are entangled, changes made to one qubit instantaneously affect the other, regardless of the distance between them. This correlation between entangled qubits enables the implementation of powerful quantum algorithms.

Interference plays a crucial role in quantum computing as well. In an environment with entangled qubits in a state of superposition, there exist waves of probabilities representing potential measurement outcomes. These waves can interfere with each other, either reinforcing or canceling each other out. Through selective interference, quantum circuits can amplify certain outcomes and cancel others, providing solutions to computational problems.

The process of computation on a quantum computer involves preparing a superposition of all possible computational states. A quantum circuit, designed by the user, selectively applies interference operations to different components of the superposition based on the desired algorithm. Through interference, many potential outcomes are eliminated, while the amplified outcomes represent the solutions to the computation.

In summary, quantum computing utilizes qubits implemented with superconducting Josephson junctions to perform computations based on the principles of superposition, entanglement, and interference. By harnessing these phenomena, quantum computers offer the potential to solve complex problems more efficiently than classical computers, opening up new frontiers in fields such as cryptography, optimization, and drug discovery.

### How fast are quantum computers compared to regular computers? Will quantum computers eventually surpass regular computers in terms of spe…

Quantum computers have gained significant attention due to their potential to revolutionize computing power. To understand how fast quantum computers are compared to regular computers, let’s examine a concrete example of speed using a search engine.

Imagine you have a box containing twenty million documents, each with a hundred words. A user enters a sequence of up to three words, and your program searches for documents containing that sequence. In the worst-case scenario where the search term doesn’t appear at all, you would need to look at all twenty million documents before providing an answer. If each document is analyzed word by word, it would take approximately 7.3 seconds to determine that the search term is not found. However, this time can vary depending on the programming language used.

In real-world scenarios, this speed may be too slow for users, especially when multiple users are accessing the database simultaneously and have to wait for each search job to complete. To address this, one solution is to create an alphabetical list of all the three-word phrases in the documents. Each triword is added to the dictionary along with a list of documents that contain it, placed in the correct alphabetical position.

When searching for or adding a triword to the dictionary, you split the dictionary in half repeatedly until you find the word or its nearest neighbor. For example, if you’re searching for the triword dog bites man, you start by opening the dictionary halfway, comparing with moose bites uncle, and continue splitting until you locate dog bites man. This process takes approximately log-base-2 of the number of triwords memory accesses to find or insert an item.

Building the dictionary involves going through every word in each document. With 100 words per document, this operation takes a perceptible amount of time. However, the dictionary only needs to be built once, and the work can be divided over time.

Searching the dictionary to find a document containing a specific triword, as mentioned before, takes about log-base-2 of 2,000,000,000 (the number of triwords) at worst. Therefore, the time required for this operation is significantly reduced compared to searching the documents individually.

This example illustrates how computers are designed to solve problems efficiently on large datasets. The initial investment of 2000 seconds in building the dictionary pays off after the 263rd query. Given that most databases are queried more than 263 times, transitioning to a giant dictionary proves to be a beneficial approach.

(Note: It’s worth mentioning that reading data from the hard disk is slower than the memory access discussed above. Additionally, the dictionary’s size might require utilizing the hard disk. Nevertheless, even with these factors considered, the time saved by using the dictionary outweighs the initial delay after approximately 300 queries.)

### Classical vs. quantum computing: What are the differences?

Classical and quantum computing are two distinct technologies with significant differences in their capabilities and operations. As new technologies emerge, it is essential to understand how they differ from the existing norms to prepare for their widespread adoption.

Classical computing has been the standard for many decades, while quantum computing is a rapidly developing technology with diverse applications in areas such as cybersecurity and modeling. Although it may take years before quantum computing becomes widely implemented, it is crucial to explore the disparities between classical and quantum computing to gain a comprehensive understanding of this emerging technology.

One fundamental difference lies in the physical conditions under which these computers operate. Quantum computers require more regulated environments due to the principles of quantum mechanics. In contrast, classical computers have less compute power, limited scalability, and use bits as their units of data, while quantum computers employ qubits.

In classical computers, data is processed in a binary manner using bits. A group of eight bits is known as a byte, and each bit can represent either a 1 or a 0, signifying on or off, true or false, or yes or no. Classical computers primarily rely on serial processing, where one operation must complete before another begins. However, parallel processing is also utilized in certain computing systems, enabling simultaneous tasks. Classical computers produce a single result as their output, given the repeatability of 1s and 0s in their binary nature.

Quantum computing follows different rules, utilizing qubits as the unit of data. Qubits can simultaneously hold values of 1 and 0, existing in multiple states simultaneously. This phenomenon is known as superposition, where properties are not defined until measurement occurs. Groups of entangled qubits can create complex computational spaces, allowing for more intricate computations. The entanglement also facilitates faster information transfer between qubits.

Classical computers rely on logic and algebra and exhibit linear power scaling with the number of transistors, representing the 1s and 0s. In contrast, quantum computers experience exponential power scaling due to the ability of qubits to represent both 1 and 0 simultaneously. The number of computations a quantum computer can perform increases exponentially with the number of qubits.

Classical computers are designed for everyday use under normal conditions, while quantum computers often require heavily regulated environments. Some quantum computers must operate at extremely low temperatures close to absolute zero, as qubits are highly sensitive to mechanical and thermal influences. Maintaining these cold operating environments ensures that the qubits retain their quantum coherence, which is crucial for accurate computations.

Data center managers should pay attention to quantum computing due to its potential opportunities and risks. Even if organizations do not plan to implement quantum computing directly, they must prepare for the external threats it may pose. Quantum computing has the potential to crack even the most advanced security measures, rendering current encryption methods vulnerable. Additionally, organizations considering quantum computers for their data centers need to plan for the required space, resources, and staffing.

In conclusion, classical and quantum computing differ significantly in their compute capabilities, data units, power scaling, and operating environments. Understanding these differences is crucial for data center managers and organizations to effectively prepare for the future impact of quantum computing and address its potential opportunities and risks.
