The ability to detect individual microwave photons is a key enabling technology for quantum computing, quantum sensing, and fundamental physics experiments. Despite recent breakthroughs in detection efficiency, existing single-photon detectors typically suffer from a limited dynamic range, making them unsuitable for measuring signals containing more than a few photons. Overcoming this limitation by developing detectors sensitive to microwave pulses spanning 1 to 100 photons would represent a major step forward, particularly towards single-shot readout of superconducting qubits without the need for parametric amplifiers. Our group has recently demonstrated a novel approach to microwave photon detection based on a microwave photon-to-electron converter, in which a superconducting tunnel junction acts as a voltage-tunable quantum absorber through photon-assisted quasiparticle tunneling. By developing an ultrasensitive charge detection technique, we have further demonstrated the detection of individual microwave photons. Building on this expertise, we now aim to explore a complementary detection strategy exploiting the extreme temperature sensitivity of diffusive Josephson junctions. By operating a junction close to its switching instability, the absorption of a few microwave photons can trigger a transition from the superconducting to the resistive state, converting energy deposition into a robust electrical signal.
