Efficient qubit measurement with a nonreciprocal microwave amplifier
F. Lecocq, L. Ranzani, G. A. Peterson +5
The act of observing a quantum object fundamentally perturbs its state, resulting in a random walk toward an eigenstate of the measurement operator. Ideally, the measurement is res…

Ultrastrong parametric coupling between a superconducting cavity and a mechanical resonator
G. A. Peterson, S. Kotler, F. Lecocq +5
We present a new optomechanical device where the motion of a micromechanical membrane couples to a microwave resonance of a three-dimensional superconducting cavity. With this arch…
