The full form of Qubit is Quantum bit. It’s used on Academic & Science ,Units in Worldwide

Quantum bit (qubit) is the smallest unit of information in a quantum computer. Qubit can hold a value of 1 or 0 as well as both values at the same time, described as superposition and simply denoted as “0+1”. The sign of this superposition is important because both states 0 and 1 have a phase relationship to each other. This superposition property is what allows quantum computers to choose the correct solution amongst millions of possibilities in a time much faster than a conventional computer.
