DEVELOPING GRAPHENE JOSEPHSON MICROWAVE SINGLE-PHOTON DETECTOR FOR QUANTUM INFORMATION SCIENCE

Abstract

Modular architectures for quantum information science (QIS) are widely seen as the leading path towards scalability. In this approach, small modular computational systems are assembled into complex, large systems through quantum network connections. In particular, modular SC (SC) QIS technology will likely require a single-photon detector (SPD) at microwave frequencies. However, such detectors remain extremely challenging because microwave photons are 105 times less energetic than optical photons. Here we propose to develop a fundamentally new type of microwave SPD based on bolometry with a dilute electron gas in graphene, enabling ultrafast readout and single-photon sensitivity down to the GHz regime.
