# Definition of quantum computing

Information processing in the realm of quantum physics is known as quantum computing. Quantum computers employ quantum bits, or qubits, which may be in a superposition of states, meaning they can represent both a 0 and a 1 simultaneously, in contrast to conventional computers which depend on bits, which are binary units of information that can either be a 0 or a 1. Additionally, it is possible for qubits to become "entangled" with one another, which means that their states will become correlated in a way that can be used to perform specific computations exponentially faster than classical computers. However, current quantum computers are still in their early stages of development and face significant technical challenges before they can realise their full potential and revolutionise fields like cryptography, materials science, and drug discovery.
