Quantum Bit (Qubit)
What is Quantum Bit (Qubit)
The smallest unit of quantum information and quantum computing’s equivalent of a traditional computer bit is called a quantum bit (qubit). Superposition is the ability of a quantum bit to exist simultaneously in many states. In contrast to a normal bit, which can only be in one of two states—1 or 0—a quantum bit can be in any of these three states: 1, 0 or 1 and 0 simultaneously. Theoretically, this enables extremely quick computation and the execution of numerous calculations simultaneously.
