Detecting the Internal Energy of Photons Through a Graphene Josephson Inductive Readout, Part 1

ORAL

Abstract

Abstract: Detectors that can resolve ultra-low photon fluxes in the infrared and at microwave frequencies are an imperative tool for applications ranging from quantum computing to radio-astronomy. Traditional photodetection tools such as MKIDs and SNSPDs rely on Cooper pair breaking, which limits both the energy resolution and bandwidth of the detector. In these talks, we will discuss a new paradigm in photodetection exploiting Graphene Josephson Junctions (GJJ). Our GJJ relies on the low heat capacity and broadband absorption of graphene, allowing for infrared single photon detection (1) and microwave bolometry at the single-photon level (2,3). Part 1 will focus on the underlying theory allowing for such a measurement, as well as the experimental setup required to measure photons based on their internal energy.
