This article lists the companies worldwide engaged in the development of quantum computing or quantum communication. Quantum computing and communication are two sub-fields of quantum information science, which describes and theorizes information science in terms of quantum physics. While the fundamental unit of classical information is the bit, the basic unit of quantum information is the qubit.
