| الوصف: | Single-photon detectors based on the superconducting transition-edge sensor (TES) are used in a number of visible to near-infrared (VNIR) applications, particularly for photon-number-resolving measurements in quantum information science. To be practical for large-scale photonic quantum computing or for future spectroscopic imaging applications in astronomy, the size of VNIR TES arrays must be increased from a few pixels to many thousands. Historically, TES arrays have been read out with multiplexed superconducting quantum interference devices (SQUIDs), but the microsecond-duration pulse signals of VNIR TESs are notoriously difficult to multiplex. In this manuscript, we introduce the kinetic inductance current sensor (KICS), a more readily scalable readout technology that exploits the nonlinear kinetic inductance in a superconducting resonator to make sensitive current measurements. KICS devices can replace SQUIDs for many applications because of their ability to measure fast, high slew-rate signals, their compatibility with standard microwave frequency-division multiplexing techniques, and their relatively simple fabrication. Here, we demonstrate the readout of a VNIR TES using a KICS with $3.7$ $\text{MHz}$ of bandwidth. We measure a readout noise of $1.4$ $\text{pA}/\sqrt{\text{Hz}}$, considerably below the TES noise at frequencies of interest, and a TES energy resolution of $(0.137 \pm 0.001)$ $\text{eV}$ at $0.8$ $\text{eV}$, comparable to resolutions observed with non-multiplexed SQUID readouts.
