Qubits

Any bit made from a quantum system, such as an electron or photon, is referred to as a quantum bit. A quantum bit, like a classical bit, must have two different states: one representing "0" and the other representing "1." A quantum bit can exist in superposition states, be exposed to incompatible measurements, and even be entangled with other quantum bits, unlike a conventional bit. Qubits are fundamentally different and far more powerful than classical bits because they can leverage the powers of superposition, interference, and entanglement.

Quantum objects that operate as qubits are required to develop quantum computers and other quantum information technologies. Many physical systems have been harnessed and controlled by scientists to behave as qubits. This allows us to match the demands of different quantum technologies to the advantages of different qubit kinds.
