Hybrid Quantum Interferometer in Bifurcation Mode as a Latching Quantum Readout
Connor D Shelly, Christopher Checkley, Victor T Petrashov
We have developed a new type of magnetometer consisting of a Hybrid Quantum Interference Device (HyQUID) that is set in a bi-stable state. We demonstrate its operation in a latchin…

Capturing Complex Behaviour in Josephson Travelling Wave Parametric Amplifiers
Tom Dixon, Jacob W. Dunstan, George B. Long +3
We present an analysis of wave-mixing in recently developed Josephson Travelling Wave Parametric Amplifiers (JTWPAs). Circuit simulations performed using WRspice show the full beha…

Existence of Shapiro Steps in the Dissipative Regime in Superconducting Weak Links
Connor D. Shelly, Patrick See, Ivan Rungger +1
We present measurements of microwave-induced Shapiro steps in a superconducting nanobridge weak link in the dissipative branch of a hysteretic current-voltage characteristic. We de…
