- Abstract summary: Josephson junctions (JJs) are ubiquitous superconducting devices, enabling high sensitivity magnetometers and voltage amplifiers.
We demonstrate single near-infrared photon detection by coupling photons to the localized surface plasmons of a graphene-based JJ.
The photon-sensitive JJ will enable a high-speed, low-power optical interconnect for future JJ-based computing architectures.

- Abstract: Josephson junctions (JJs) are ubiquitous superconducting devices, enabling
high sensitivity magnetometers and voltage amplifiers, as well as forming the
basis of high performance cryogenic computer and superconducting quantum
computers. While JJ performance can be degraded by quasiparticles (QPs) formed
from broken Cooper pairs, this phenomenon also opens opportunities to
sensitively detect electromagnetic radiation. Here we demonstrate single
near-infrared photon detection by coupling photons to the localized surface
plasmons of a graphene-based JJ. Using the photon-induced switching statistics
of the current-biased JJ, we reveal the critical role of QPs generated by the
absorbed photon in the detection mechanism. The photon-sensitive JJ will enable
a high-speed, low-power optical interconnect for future JJ-based computing
architectures.

Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins.
We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry.
Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.
