Can QPUs (Quantum Processing Units) built on with electrons in superconducting graphene ever be faster than photons in integrated nanophotonics?
There are integrated parametric single-photon emitters and detectors.
Is there a lower cost integrated nanophotonic coherent light source for [quantum] computing than a thin metal wire?
