Quantum Information Technologies: Coherent Conversion Between Microwave and Optical Photons—An Overview of Physical Implementations (Adv. Quantum Technol. 1/2020)

Abstract

Spatially separated quantum technologies will need to communicate using optical channels, rather than at microwave frequencies which correspond to the energy scales of superconducting qubits. The theoretical description underlying the different physical implementations of up-conversion is the beam-splitter Hamiltonian. A classical driving field is depicted as a Gaussian field distribution and the quantized pulses are shown in red (microwave) and blue (optical). In article number 1900077, Florian Sedlmeir, Harald G. L. Schwefel, and co-workers review current experimental implementations.
