Verkin Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine popup.description2 Single photon counters are key devices in new quantum technologies, as they play a crucial role both for coherent communication between qubits in quantum computers and for secure quantum communication. These are the most complex devices because they operate at the limit of physically possible sensitivity. The project proposes to improve the microwave single photon counter based on a superconducting flux qubit with a widely controlled reception frequency and a much higher counting rate. This will improve the performance of quantum communication systems and prepare them for future upgrades with modern superconducting materials. At this stage the goal of the project is to develop theoretical description of a single-photon counter and to provide numerical calculations of counter elements parameters.  Product Description popup.authors popup.nrat_date 2022-03-09 Close
