Q. What is the term for the fundamental unit of information in quantum computing that can represent multiple states at once?
Answer: Qubit
Notes: In quantum computing, the basic unit of information is called a qubit, which can exist in a superposition of states, allowing it to represent both 0 and 1 simultaneously. This property enables quantum computers to perform complex calculations much faster than classical computers. Additionally, qubits can be entangled, meaning the state of one qubit can depend on the state of another, leading to enhanced computational power. Superconductors are often used in quantum circuits, while classical computers rely on semiconductors.
