### When will quantum computers finally break into the market? – Physics World

The future of quantum computers and their entrance into the mainstream market is a topic that generates a lot of hype and excitement. Predicting when this will happen and what these computers will be useful for is a challenging task. One approach to understanding the development of new technologies is the Gartner hype cycle, which shows the evolution of expectations surrounding a particular technology over time. This cycle consists of several stages: a technology trigger, a peak of inflated expectations, a trough of disillusionment, a slope of enlightenment, and a plateau of productivity.

The Gartner hype cycle suggests that there will be both winners and losers in the field of quantum computing. Some companies may run out of money due to scaling issues, poor execution, bad timing, or management mistakes. However, the current investment in quantum computing is substantial, with an estimated £3.2 billion invested in 2022. Some companies have even received product orders, such as ORCA and its ORCA PT-1 device that operates at room temperature.

Despite the financial support and product orders, many potential customers may not fully grasp the benefits of quantum computers until they see them in action. The challenge lies in determining the best applications for this technology. Quantum computers excel at solving problems that classical computers struggle with or cannot solve at all. One well-known application is factoring large numbers, which quantum computers can do exponentially faster than classical algorithms. This capability raises concerns about the security of existing encryption algorithms, as quantum computers may be able to break them.

Governments and organizations, including the US National Institute of Standards and Technology, are aware of this issue and have initiated programs to develop new encryption standards resistant to quantum attacks. In addition to breaking encryption, quantum computers are expected to excel at solving optimization problems, simulating quantum systems, and improving machine-learning algorithms.

### What is Quantum Computing? | IBM

Quantum computing is a revolutionary approach to computation that utilizes the principles of quantum mechanics to perform complex calculations. Unlike classical computers that use bits to process information, quantum computers employ qubits, which are capable of existing in multiple states simultaneously.

The physical components of an IBM Quantum processor are quite small, similar in size to a laptop wafer. However, the overall quantum hardware system is much larger, comparable to the size of a car. The system primarily consists of cooling mechanisms designed to maintain the ultra-cold operational temperature required for the superconducting processor.

To prevent a phenomenon called decoherence and preserve the quantum states, quantum processors need to be extremely cold, around a hundredth of a degree above absolute zero. Super-cooled superfluids are employed to achieve these ultra-low temperatures. At such frigid conditions, certain materials exhibit a significant quantum mechanical effect known as superconductivity, where electrons can move through them without encountering any resistance.

When electrons pass through superconductors, they form Cooper pairs. These pairs possess the ability to traverse barriers, such as insulators, through a process called quantum tunneling. Josephson junctions are created by placing two superconductors on either side of an insulator, and they are utilized as superconducting qubits in IBM’s quantum computers.

Control over the behavior of qubits is essential in quantum computing. IBM achieves this by directing microwave photons at the Josephson junctions, enabling the control, manipulation, and reading of individual units of quantum information.

A single qubit alone does not offer significant computational capabilities. However, qubits can be placed in a state of superposition, where they represent a combination of all possible configurations simultaneously. By utilizing groups of qubits in superposition, complex and multidimensional computational spaces can be created. This allows for the representation of complex problems in novel ways within these spaces.

Quantum entanglement is a phenomenon in which the behavior of two separate qubits becomes correlated. Changes made to one qubit directly affect the other, regardless of the distance between them. This property of entanglement has significant implications for quantum computing.

In an environment where entangled qubits are in a state of superposition, there exist waves of probabilities that represent the potential outcomes of a measurement. Interference occurs when these waves interact with each other. They can either build up and amplify at specific outcomes or cancel each other out through peaks and troughs interacting. These two forms of interference are crucial for quantum computations.

The process of computation on a quantum computer involves preparing a superposition of all possible computational states. A user prepares a quantum circuit, which selectively applies interference to the components of the superposition based on a specific algorithm. Through interference, many possible outcomes are canceled out, while others are amplified. The amplified outcomes represent the solutions to the computation.

In summary, quantum computing harnesses the principles of quantum mechanics to process information using qubits. These qubits are realized through superconducting Josephson junctions, which are controlled using microwave photons. The properties of superposition, entanglement, and interference enable the creation of complex computational spaces and the extraction of meaningful results from quantum computations.

The ability to connect qubits among processors will require advances in quantum communications, such as coherent qubit transfer over long distances using fiber-optic networks or satellite-based networks.

The industry is also moving away from the concept of noisy intermediate-scale quantum (NISQ), which suggested that chips with just a few hundred qubits could perform useful computing despite noise disruptions. Instead, companies are exploring error correction methods and techniques to make quantum computers fault tolerant. IBM, for example, is developing algorithms to characterize and subtract noise, while IonQ is mitigating noise by understanding and controlling the sources of errors.

While hardware progress is significant, attention is also being given to software development. Many researchers believe that more tools and programming frameworks are needed to enable flexible computation routines. Circuit-based quantum computing, where data is processed through a series of predefined quantum operations, limits the ability to loop steps and run different subroutines. Companies like Horizon Quantum Computing and Algorithmiq are developing programming tools that allow for more flexible computation.

In terms of global competition, various countries and companies are making strides in quantum computing. Baidu and Alibaba in China are working on superconducting qubits and opening access to quantum computing resources. Fujitsu in Japan plans to offer access to its 64-qubit quantum computer for applications in materials development, drug discovery, and finance. India is investing heavily in photonics technologies and exploring the potential of qudit photonics computing, which expands the data encoding capabilities of qubits.

While competition is fierce, the quantum computing field remains largely collaborative for now, with different technologies at different levels of maturity. However, as the field progresses, consolidation may occur. The overall progress in quantum computing is rapid, and experts anticipate the development of general-purpose quantum computers earlier than expected a few years ago.

The day when a powerful quantum computer can crack the most commonly used encryption methods is known as Q-day. This event would have massive implications for internet companies, banks, governments, and personal privacy. While quantum computers are currently too unstable to perform complex operations for extended periods, researchers are working towards developing more robust machines.

In 1994, mathematician Peter Shor devised an algorithm that, when run on a powerful quantum computer, could crack the RSA encryption protocol used to secure online transactions. The RSA algorithm takes advantage of the fact that multiplying two large prime numbers is easy, while reversing the calculation is computationally difficult for classical computers. Shor demonstrated that a quantum computer could perform this reverse calculation with relative ease. Researchers are also exploring hybrid classical-quantum computing approaches to tackle encryption methods.

The world’s leading powers are engaged in a race to develop quantum computers due to the potential benefits and the fear of falling behind. Quantum computers not only have the capability to break existing encryption methods but also offer possibilities for securing communications in a quantum world. Governments, corporations, and venture capitalists are investing heavily in the commercialization of quantum technology. Companies like IBM, Google, Microsoft, and Honeywell, as well as numerous startups, are actively involved in quantum research and development.

To understand quantum computing, it’s essential to grasp the functioning of classical computers. Classical computing relies on bits, which can be in one of two binary states: off or on (0 or 1). A sequence of eight bits forms a byte, capable of storing more data than a single bit. However, the reliability of individual bits is crucial for the integrity of computer systems.

Quantum computing operates using quantum bits, or qubits, which exist in a quantum state where they can be simultaneously considered both on and off until measured. Qubits can be arranged in ways that maximize the probability of finding the correct answer to a problem. Quantum algorithms are at the core of quantum computing, allowing the exploration of multiple paths simultaneously. However, maintaining the stability of qubits is a major challenge. Quantum computers require a cryogenic environment near absolute zero to minimize interaction with the surrounding environment, which can disrupt the quantum state.

Despite the progress made in quantum computing, there are several hurdles to overcome. The fragility of qubits and the resulting noise from the environment limit the time they can stay in a quantum state. Decoherence, the loss of quantum coherence, reduces the reliability of quantum computers. This limitation necessitates the use of large and sophisticated machines to house just a few hundred qubits.

The race to develop quantum technology is driven by the economic potential and geopolitical rivalry. Quantum computing could bring significant advancements in various fields, such as materials science, drug development, financial trading strategies, and secure communication methods. Governments recognize the strategic importance of quantum technology and are increasing investments in research and development. While the first company to develop a reliable quantum computer could generate billions in revenue, the security implications of quantum computers also concern governments. The RSA encryption method, widely used to secure digital data, becomes vulnerable to quantum machines.

Efforts are being made to develop new cryptography systems that are secure against both quantum and classical computers. However, implementing these systems will take time, and companies with sensitive data should begin preparing for Q-day today. Despite the challenges, researchers are confident that with ongoing innovations, scalable quantum computers with a million qubits could be achieved within years rather than decades.

While private sector investors may experience uncertainty and a potential quantum winter, the competition between the US and China will continue to drive the development of robust quantum computers.

This unique characteristic of qubits enables quantum computers to perform complex computations in parallel, potentially solving problems that are currently intractable for classical computers.

There are several different approaches to building a quantum computer, each employing a different type of qubit technology. One such approach is gate-based ion trap processors. In this method, qubits are implemented using the electronic states of charged atoms, or ions, that are confined and suspended above a microfabricated trap using electromagnetic fields. Quantum gates, which are analogous to gate operations in traditional electronics, are applied to the trapped ions using lasers to manipulate their electronic states. It’s worth noting that trapped ion qubits are sourced from nature rather than being artificially manufactured.

Another approach is gate-based superconducting processors, which utilize superconducting electronic circuits operating at cryogenic temperatures. Superconductivity is a property exhibited by certain materials at extremely low temperatures, where electrical resistance becomes zero and magnetic flux fields are expelled. Superconducting qubits are built with superconducting circuits and can persistently maintain an electric current through a loop of wire without any power source.

Photonic processors are another avenue for quantum computing. These devices manipulate light for computational purposes. Quantum photonic computers utilize quantum light sources that emit squeezed-light pulses, with qubits represented by modes of a continuous operator, such as position or momentum.

Neutral atom processors, similar to trapped ion technology, use light instead of electromagnetic forces to trap and position the qubits. The key difference is that neutral atom processors operate at room temperatures, making them more accessible and easier to maintain.

Rydberg atom processors exploit the properties of Rydberg atoms, which are excited atoms with electrons that are further away from the nucleus. These qubits offer strong and controllable atomic interactions that can be tuned by selecting different states. Rydberg atoms exhibit exaggerated responses to electric and magnetic fields, providing a unique advantage for quantum computation.

Lastly, quantum annealers are specialized systems that use a physical process to place the qubits in an absolute energy minimum. The hardware then gently alters the system’s configuration to match the problem that needs to be solved. Quantum annealers excel at solving specific cases and can accommodate a larger number of qubits compared to gate-based systems.

In conclusion, quantum computing is a rapidly advancing field with multiple avenues for qubit technology. Gate-based ion trap processors, gate-based superconducting processors, photonic processors, neutral atom processors, Rydberg atom processors, and quantum annealers all represent different approaches to realizing the potential of quantum computing.
