A junction for single-photon detection Josephson junctions are simple superconducting devices comprising an insulator or semiconductor separating two superconducting regions. They form the workhorse of superconducting technologies and are exquisitely sensitive to magnetic field. One long-sought proposal has been to use these devices to detect light. Walsh et al. have realized a photosensitive Josephson junction based on graphene that is capable of sensing single infrared photons. Such a…

Bolometer operating at the threshold for circuit quantum electrodynamics.

A bolometer is experimentally demonstrated that operates at the threshold for circuit quantum electrodynamics, with a noise-equivalent power of 30 zeptowatts per square-root hertz, comparable to the lowest value reported so far, and the minimum observed time constant is well below the dephasing times for superconducting qubits and matches the timescales of currently used readout schemes.
