If quantum computers are to fulfill the promise of solving problems faster or which are too complex for classical supercomputers, then quantum information needs to be communicated between multiple processors.

Modern computers have different interconnected components such as a memory chip, a Central Processing Unit and a General Processing Unit. These need to communicate for a computer to function.

Current attempts to interconnect superconducting quantum processors use “point-to-point” connectivity. This means they require a series of transfers between nodes, compounding errors.
