## Description

- description: Single-photon detectors (SPDs) offer remarkable capabilities for highly-sensitive
    detection of electromagnetic radiation, which are crucial in applications such
    as radio astronomy, quantum information, and spectroscopy. To achieve high performance,
    state-of-the-art SPDs often rely on the photon-induced breaking of Cooper pairs
    in superconductors. However, extending SPD to a wider electromagnetic spectrum
    will require novel superconducting materials with lower carrier densities. The
    presumably unconventional superconductivity in magic-angle twisted bilayer graphene
    (MATBG) holds great promise with its unprecedentedly low carrier density of ~
    1011 cm–2 that is ~ 5 order of magnitude lower than conventional superconductors.
    To fully exploit these unique superconducting properties for quantum sensing,
    here, we demonstrate a proof-of-principle experiment to detect single near-infrared
    photons up to 700 mK by voltage biasing a MATBG device near its superconducting
    phase transition. Our work offers insights on the MATBG-photon interaction and
    opens new opportunities in developing novel quantum sensors based on low-carrier
    density graphene-based superconductors.
