Detecting single-Infrared-photon by graphene Josephson junction

ORAL

Abstract

Single-photon detector is a key enabling technology in quantum information processing, cryotography, and deep space communication. However, detecting low frequency photons is challenging because of their vanishingly small energy. Here we will present the concept of a graphene-based Josephson junction single-photon detector that can potentially perform in a wide electromagnetic spectrum. We will focus on our experimental results of the Josephson junction switching induced by single-infrared-photon. We will conclude by its applications in quantum information science, radio astronomy, as well as dark matter detection.
