What is meant by the term quantum interference?

Quantum interference refers to a phenomenon that occurs in the context of quantum mechanics. It is most commonly observed in experiments involving the two-slit setup. In this experiment, an interference pattern is observed when particles, such as photons or electrons, are sent through two closely spaced slits and allowed to hit a screen behind them.

In classical physics, one would expect that the pattern on the screen would be a simple combination of the wavefunctions associated with each slit individually. However, in quantum mechanics, the interference pattern is more complex. It is not just a result of adding the wavefunctions of the particles passing through each slit; instead, there is a mixed term that contributes to the pattern.

What makes this phenomenon particularly intriguing is that it persists even when the number of particles is reduced to a single photon or electron at a time. This raises the question: What is the single particle interfering with to produce a pattern on the screen that is different from what would be expected classically?

The answer lies in the concept that the particle interferes with itself. In other words, the single particle exhibits wave-particle duality and can simultaneously behave as both a particle and a wave. As it passes through the two slits, it undergoes a superposition, existing in multiple states or paths simultaneously. These different paths interfere with each other, resulting in the observed interference pattern.

The significance of quantum interference becomes evident when considering the Feynman integral, as explained by physicist Richard Feynman. The Feynman integral involves a sum or integral over various paths, each associated with an amplitude. These amplitudes interfere with each other, and this interference is a characteristic feature of quantum mechanical effects. In classical physics, only the path with the smallest Lagrangian action would contribute to the integral.

By studying quantum interference, scientists gain insights into the fundamental nature of quantum mechanics. It challenges our classical intuitions and highlights the unique behavior of particles at the quantum level. The phenomenon of quantum interference has profound implications for various fields, including quantum computing, quantum information processing, and the development of new technologies that harness quantum effects.

In summary, quantum interference refers to the interference pattern observed when particles exhibit wave-particle duality and interfere with themselves. This phenomenon is distinct from classical mechanics and is characterized by complex interference patterns that arise even with single particles. The two-slit experiment exemplifies this phenomenon, and it has been further elucidated through concepts such as the Feynman integral. Quantum interference plays a crucial role in our understanding of quantum mechanics and has far-reaching implications for technological advancements in the field.

What is a Quantum Computer? – Quandela – Medium

Quantum computing is a revolutionary technology with the potential to transform society. Despite its significance, many people are unfamiliar with what quantum computing actually is. In this article, we will provide a simple explanation of quantum computers and how they work, even if you don’t have a background in science.

A quantum computer is a device that utilizes the principles of quantum mechanics to perform calculations at a much faster rate than traditional computers. By faster, we mean that these computers can solve problems that would take millions of years for the best supercomputers today. These problems are not merely mathematical puzzles but real-world challenges that can have a profound impact on our lives.

For example, quantum simulations of chemical reactions can help discover life-saving medicines, advanced materials, and sustainable manufacturing processes. Quantum algorithms have the potential to revolutionize artificial intelligence, while quantum cryptography can provide unbreakable data encryption based on the laws of physics. The practical applications of quantum computing have led to a great deal of hype in the industry, with companies seeking customers and funding. To truly understand the underlying technology, it’s important to grasp some fundamental physics.

Quantum mechanics serves as the foundation for quantum computing. It is a scientific theory that describes the behavior of the basic building blocks of our universe, such as atoms, electrons, and photons. There are two essential terms to define: a quantum system is something that can be explained using quantum mechanics, and a quantum state is the mathematical description of a quantum system.

To understand quantum computing, you need to be familiar with three key principles of quantum mechanics: entanglement, interference, and superposition.

Entanglement occurs when a group of particles becomes connected in a way that measuring one particle instantly affects the others, regardless of the distance between them. This phenomenon is not observable in our everyday world. An analogy to explain entanglement is a pair of quantum coins. These coins exist in a combination of heads and tails until one is measured. If one coin is found to be heads, the other coin’s state instantly becomes tails.

Interference is the phenomenon where overlapping waves combine or cancel each other out. This concept is employed in noise-canceling headphones, which emit sound waves that interfere destructively with background noise. Quantum particles can also exhibit interference because they behave like waves.

Superposition is the idea that a quantum state can be described as the sum of other quantum states. This is similar to waves, which can be described as the sum of multiple waves. In the context of entanglement, the quantum coin exists in a superposition of heads and tails.

While quantum mechanics is highly accurate, engineers typically rely on classical physics to design everyday objects like cars and bridges. Classical physics provides simplified rules and approximations to describe the behavior of familiar things like heat, sound, motion, and gravity. Quantum mechanics is necessary to explain the behavior of small-scale objects like atoms, but when many quantum objects interact, their collective behavior can often be described using classical physics. This is why classical physics is used to describe the large-scale world we live in.

Now let’s dive into the fundamental components of quantum computers, known as qubits. In classical computers, information is represented using bits that have a value of either 0 or 1. In contrast, qubits are the quantum version of bits. Physically, a qubit is a two-level quantum system. One example of a qubit is a photon that can be sent down one of two optical fibers. If the photon is in the first fiber, the qubit is in the state |0>. If it’s in the second fiber, the qubit is in the state |1>. Measuring the state of a qubit collapses its superposition, and it will be found in either the first or second fiber.

Quantum computers generally consist of three stages: initialization, manipulation, and measurement. During initialization, the qubits are given known values. In the manipulation stage, a quantum circuit applies mathematical operations to the qubits using interference and entanglement. Finally, in the measurement stage, the quantum states of the qubits are measured to obtain the results of the calculation.

At the end of a calculation, the qubits in a quantum computer exist in a superposition of all possible outcomes. When measured, the superposition collapses, and one of the possible outcomes is obtained as the answer. Quantum algorithms can be designed so that the wrong answers interfere destructively and cancel out, leaving only the right answers. Entanglement plays a crucial role in connecting qubit superpositions to perform useful calculations.

By repeating the circuit and measuring the qubits multiple times, a graph representing the likelihood of each possible outcome can be constructed. This graph, known as a probability distribution, serves as the final result of the quantum calculation.

The process of manipulating probabilities with superposition, interference, and entanglement is fundamentally different from how traditional computers operate. Quantum computers are not inherently better than classical computers; they simply work differently. Quantum computers excel at tasks like designing medicines and solving complex problems, while classical computers are better suited for everyday tasks. As a result, quantum computers are expected to coexist with classical computers rather than replacing them entirely. Many famous quantum algorithms combine both quantum and classical techniques to solve problems.

This article provides a basic understanding of what quantum computers are and how they operate. In future articles of this series, we will delve deeper into the inner workings of quantum computers without overwhelming you with technical jargon.
