- Abstract: The detection of individual quanta of light is important for quantum
computation, fluorescence lifetime imaging, single-molecule detection, remote
sensing, correlation spectroscopy, and more. Thanks to their broadband
operation, high detection efficiency, exceptional signal-to-noise ratio, and
fast recovery times, superconducting nanowire single-photon detectors (SNSPDs)
have become a critical component in these applications. The operation of SNSPDs
based on conventional superconductors, which have a low critical temperature
($T_c$), requires costly and bulky cryocoolers. This motivated exploration of
other superconducting materials with higher $T_c$ that would enable
single-photon detection at elevated temperatures, yet this task has proven
exceedingly difficult. Here we show that with proper processing, high-$T_c$
cuprate superconductors can meet this challenge. We fabricated superconducting
nanowires (SNWs) out of thin flakes of Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$ and
La$_{1.55}$Sr$_{0.45}$CuO$_4$/La$_2$CuO$_4$ (LSCO-LCO) bilayer films and
demonstrated their single-photon response up to $25$ and $8$ K, respectively.
The single-photon operation is revealed through the linear scaling of the
photon count rate (PCR) on the radiation power. Both of our cuprate-based
SNSPDs exhibited single-photon sensitivity at the technologically-important
$1.5$ ${\mu}$m telecommunications wavelength. Our work expands the family of
superconducting materials for SNSPD technology, opens the prospects of raising
the temperature ceiling, and raises important questions about the underlying
mechanisms of single-photon detection by unconventional superconductors.
