The basic unit of quantum information is,

  • A.QUBIT
  • B.BIT
  • C.BYTE
  • D.GIGABIT

Answer: A

The basic unit of quantum information is the QUBIT.

A qubit, or quantum bit, is a two-state quantum system that can exist in a superposition of 0 and 1 at the same time, and qubits can be entangled with one another. These properties are what quantum computing and quantum communication exploit.

The bit is the unit of classical information, which is always either 0 or 1. A byte is eight classical bits and a gigabit is a billion of them, so none of these is a quantum unit.
