Moving quantum information

Memory, computation, and other functions are carried out by various components in a conventional classical computer.Interconnects, which are wires that move electrons around in a computer processor, are used to move electronic information between these components.

Electronic information is encoded and stored as bits, which have a value of 1 or 0.Quantum information, however, is more intricate.

Quantum information can also be both 0 and 1 at the same time—a phenomenon known as superposition—instead of just having a value of 0 or 1.Photons, which are light-emitting particles, are also capable of carrying quantum information.Quantum information is fragile and cannot be transported using standard protocols because of these additional complexity.
