UPSC Prelims 2022 question on Qubit Quantum Computing

Analysis

Quantum computing holds the promise to solve some of our planet's biggest challenges in the areas of environment, agriculture, health, energy, climate, materials science, and others.

Just as bits are the fundamental object of information in classical computing, qubits (quantum bits) are the fundamental object of information in quantum computing. While a bit, or binary digit, can have a value either 0 or 1, a qubit can have a value that is either 0, 1 or a quantum superposition of 0 and 1.

The term 'qubit' is used exclusively in the context of Quantum Computing.
