Which one of the following-is the context in which the term “qubit” is mentioned ?
- A. Cloud Services
- B. Quantum Computing
- C. Visible Light Communication Technologies
- D. Wireless Communication Technologies
Answer: B
Explanation
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 we haven’t encountered yet. For some of these problems, classical computing is increasingly challenged as the size of the system grows. 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. Hence option (b) is the correct answer.
