SEE: (TechRepublic) China is already actively involved in quantum communications, among others, and the country's efforts are set to increase further. China said one goal of the plan is to create a long-distance and high-speed quantum communication system that is compatible with classical communication technology. Quantum networks, which are at the core of quantum communication systems, enable physically separated quantum devices to exchange information in the form of quantum bits, or qubits. Although still in the very early stages, these networks are generating a lot of enthusiasm in the research community: for example, a network connecting many small quantum devices together could start solving the problems that are currently impossible to run on a single quantum computer.
