Which one of the following is the context in which the term "qubit" is mentioned?

Answer: B. The term 'QUBIT' is mentioned in the context of QUANTUM COMPUTING. A QUBIT (quantum bit) is the basic unit of quantum information, analogous to a classical bit. Unlike a classical bit which is either 0 or 1, a qubit can exist in SUPERPOSITION of 0 and 1 simultaneously. Qubits can also be ENTANGLED with each other, enabling quantum parallelism. Physical implementations of qubits include: - Superconducting circuits (IBM, Google) - Trapped ions (IonQ, Honeywell) - Photons (PsiQuantum) - Neutral atoms (QuEra, Atom Computing) - Topological qubits (Microsoft) The 'quantum supremacy' achievements (Google's Sycamore 2019 with 53 qubits, China's Jiuzhang) demonstrate the computational power of multi-qubit systems on specific tasks. India launched the National Quantum Mission in 2023 with the goal of building 50-1000 qubit systems. Distractors fail: (A) Cloud services use bits and bytes. (C) Visible light communication uses photons but does not use qubits. (D) Wireless tech uses RF spectrum. Source: National Quantum Mission India / IEEE Computer Society quantum computing references.
