Explanation

A "qubit" (quantum bit) is the basic unit of information in quantum computing. Unlike a classical bit, which can only represent a 0 or a 1, a qubit can represent 0, 1, or a superposition of both 0 and 1 simultaneously. This property, along with entanglement, allows quantum computers to perform certain calculations exponentially faster than classical computers. Therefore, the term "qubit" is directly associated with Quantum Computing.
