Quantum computing is a form of computing that uses quantum-mechanical phenomena, such as superposition and entanglement, to perform operations on data. It is seen as an advancement of classical computing, in which the basic unit of information is the bit, which is represented by either 0 or 1. In quantum computing, the basic unit of information is the qubit, which can exist in both 0 and 1 states at the same time — a phenomenon known as superposition. This opens up the possibility of greatly increased processing power and speed, as well as improved accuracy of calculations.
