Quantum Computing Utilizing Microwave Photons
High-precision instrumentation has been shown to measure the arrival of microwave photons sans destroying the quantum information encoded. The Swiss Federal Institute of Technology and University of Tokyo have shown the detection of the photon’s arrival via its cavity-qubit reflection. Though not a completely new concept, use of microwave photons has previously ended with the detected photon destroyed. Enter quantum non-demolition, or QND. With continued research, the end-result could be microwave quantum computing enabled completely by photons. April 23, 2018.
