DWC Investigators Schwefel and Lambert publish their invited review on “Coherent Conversion Between Microwave and Optical Photons–An Overview of Physical Implementations” in Advanced Quantum Technologies and are featured on the cover.
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, Nicholas Lambert, Harald G. L. Schwefel, and co‐workers review current experimental implementations.
