## Description

- description: Sensitive photodetectors showing large quantum efficiencies and broad
    dynamic ranges are essential components for on-chip integrated photonic quantum
    platforms and for probing quantum correlations in metrological sources. However,
    at terahertz (THz) frequencies, this is a very challenging task owing to the lack
    of high-absorption materials and thermal effects that impact their noise figure.
    Here, we develop antenna-coupled tunnel field-effect transistors, based on multilayer
    graphene/hBN/bilayer graphene/hBN that detect multiwavelength beams at frequencies
    ∼3 THz with record performances. We reach noise-equivalent powers of ∼10−12 WHz−1/2,
    a power dynamic range exceeding 5 orders of magnitude, limited by the maximum
    output power (0.8mW) of the employed source, and a minimum detectable power at
    the nW-level, in a frequency-scalable device architecture. Our results open intriguing
    perspectives for the statistical analysis of quantum intensity correlations in
    nonclassical light sources operating in the underexploited THz frequency gap,
    between technologically mature domains (microwave, visible, near-infrared) that
    currently dominate the field of quantum technologies.
