New publication: “Using Geometry to Sense Current”
We describe a superconducting three-terminal Y-shaped device that uses a simple geometric effect known as current crowding to sense the flow of current and actuate a readout signal. A complete description... Read more >>

New Paper: “nanoSQUID operation using kinetic rather than magnetic induction”
We report on a method of nanoSQUID modulation which uses kinetic inductance rather than magnetic inductance to manip-ulate the internal fluxoid state. We produced modulation using injected current rather than... Read more >>

24-picosecond single-photon timing jitter in saturated SNSPDs – New Paper in IEEE Quantum Electronics
In our new paper, to appear in the IEEE Jornal of Selected Topics in Quantum Electronics (JSTQE), we have demonstrated fully-saturated nanowire single-photon detectors with 24 ps jitter. Furthermore we... Read more >>

New paper: “Universal scaling of the critical temperature for thin films near the superconducting-to-insulating transition” accepted to Phys. Rev. B
[preprint] [supp. info.] We reported that the superconducting properties scale universally close to the superconducting-to-insulating transition in thin films. This universal behavior was found useful not only for the fundamental... Read more >>
