Q. Which one of the following is the context in which the term “qubit” is mentioned?

Explanation : 

Qubit

The term “qubit” is mentioned in the context of Quantum Computing. A qubit, or quantum bit, is the fundamental unit of quantum information—the quantum version of the classical binary bit. Unlike a classical bit, which can be in one of two states (0 or 1), a qubit can be in a superposition of both states simultaneously, thanks to the principles of quantum mechanics.

Quantum Computing and its Unique Capabilities

This property of superposition, along with other quantum phenomena like entanglement, allows quantum computers to process information in ways that are fundamentally different from classical computers. Quantum computers have the potential to solve certain types of problems much more efficiently than classical computers, including those related to cryptography, optimization, and simulation of quantum systems.

Advancements and Challenges of Quantum Computing

Quantum computing is a rapidly developing field, with significant research and investment from both the public and private sectors. It holds the promise of significant advancements in various areas of science and technology, although practical and widespread quantum computing is still an emerging technology and faces many technical challenges before it becomes mainstream.
