Frequently asked questions
Welcome to our FAQ section! Here you can find answers to some of the most commonly asked questions around quantum science.
Quantum physics is a branch of physics that studies the behavior of matter and energy on the smallest scales. It differs from classical physics in that it takes into account the wave-like properties of matter and energy, and introduces uncertainty into the measurement process.
The uncertainty principle is a fundamental principle of quantum mechanics that states that it is impossible to know both the exact position and momentum of a particle at the same time. This principle affects our understanding of the quantum world by introducing inherent uncertainty into measurements and challenging our classical intuitions about the behavior of matter and energy.
Entanglement is a phenomenon in which two or more particles become linked in such a way that the state of one particle is dependent on the state of the others, regardless of the distance between them. The exact mechanism behind entanglement is still not fully understood, but it has been observed and demonstrated experimentally.
Qubits are the basic unit of information in a quantum computer. Unlike classical bits, which can only be in one of two states (0 or 1), qubits can be in multiple states at the same time, allowing quantum computers to perform certain calculations much faster than classical computers. The superposition and entanglement properties of qubits are key to their computational power.
There are many potential applications of quantum physics, including in fields such as cryptography, materials science, drug discovery, and energy production. Quantum computers could help solve problems that are currently intractable on classical computers, while advances in quantum sensing and imaging could enable new medical diagnostic tools and more precise measurements of physical phenomena.
Quantum teleportation involves the transfer of quantum information from one location to another using entanglement. However, it does not involve the physical transfer of matter or energy, and therefore cannot be used for faster-than-light communication. The principle of causality, which states that no effect can travel faster than the speed of light, prevents this.
Quantum computing is still in its early stages of development, and practical quantum computers capable of performing useful calculations beyond the reach of classical computers are not yet widely available. However, there has been rapid progress in recent years, and there are already several companies and research groups working on building and testing quantum computers. It is difficult to predict when practical quantum computers will be widely available, but it is likely to be several years or even decades before they become commonplace.
