Nonreciprocal microwave signal processing with a Field-Programmable Josephson Amplifier
F. Lecocq, L. Ranzani, G. A. Peterson +4
We report on the design and implementation of a Field Programmable Josephson Amplifier (FPJA) - a compact and lossless superconducting circuit that can be programmed \textit{in sit…
Optical probing of mechanical loss of a Si_{3}N_{4} membrane below 100 mK
R. Fischer, N. S. Kampel, G. G. T. Assumpção +5
We report on low mechanical loss in a high-stress silicon nitride (Si_{3}N_{4}) membrane at temperatures below 100 mK. We isolate a membrane via a phononic shield formed within a s…
Hybrid quantum systems with trapped charged particles
Shlomi Kotler, Raymond W. Simmonds, Dietrich Leibfried +1
We study theoretically the possibilities of coupling the quantum mechanical motion of a trapped charged particle (e.g. ion or electron) to quantum degrees of freedom of superconduc…
Sideband Cooling Beyond the Quantum Limit with Squeezed Light
Jeremy B. Clark, Florent Lecocq, Raymond W. Simmonds +2
Quantum fluctuations of the electromagnetic vacuum impose an observable quantum limit to the lowest temperatures that can be reached with conventional laser cooling techniques. As…
Observation of Strong Radiation Pressure Forces from Squeezed Light on a Mechanical Oscillator
Jeremy B. Clark, Florent Lecocq, Raymond W. Simmonds +2
Quantum enhanced sensing is a powerful technique in which nonclassical states are used to improve the sensitivity of a measurement. For enhanced mechanical displacement sensing, sq…
