What is Quantum Bit (Qubit)?

As it relates to the field of quantum computing, a quantum bit (qubit) is the basic unit of measurement similar to the classic binary bit that is used in traditional computing. Qubits make use of superposition states such as quantum entanglement and quantum superposition to allow quantum computers to operate in a widely used manner. Qubits help facilitate the use of post-quantum cryptography or quantum-resistant computing and other related technologies. Through the use of qubits, quantum computing frameworks are theorized to process computations much faster and more efficiently than their traditional counterparts.
