qubit
Entangled information unit
A qubit is the basic unit of information in quantum computing, analogous to the bit in classical computing.
While a classical bit holds either 0 or 1, a qubit can exist in a superposition of both states simultaneously until measured.
This property, along with entanglement between qubits, enables quantum computers to perform certain calculations exponentially faster than classical machines.
