Which one of the following is the context in which the term “qubit” is mentioned?
✓ Correct answer: b) Quantum Computing
ExplanationQuantum computers are machines that use the properties of quantum physics to store data and perform computations.A classical computer performs operations using classical bits, which can be either 0 or1. Quantum computer uses quantum bits or Qubits, which can be both 0 and 1 at the same time.Qubits (or quantum bits) are the units of computation in quantum computers.They take advantage of quantum mechanics characteristics, which regulate how matter behaves at the atomic level.Quantum computers are faster, more accurate, & energy efficient.Two important phenomena of quantum physics that are used to achieve functioning of quantum computing are:1. Superimposition: Each quantum bit (basic unit of information in a quantum computer) can represent both a 1 and a 0 at the same time, which is known as superposition.2. Quantum Entanglement: Subatomic particles become “entangled” (connected) in quantum entanglement, which means that any change in one upsets the other, even though they are at opposite ends of the universe.67
