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…
Direct observation of deterministic macroscopic entanglement
Shlomi Kotler, Gabriel A. Peterson, Ezad Shojaee +9
Quantum entanglement of mechanical systems emerges when distinct objects move with such a high degree of correlation that they can no longer be described separately. Although quant…
Microwave measurement beyond the quantum limit with a nonreciprocal amplifier
F. Lecocq, L. Ranzani, G. A. Peterson +6
The measurement of a quantum system is often performed by encoding its state in a single observable of a light field. The measurement efficiency of this observable can be reduced b…
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…
Visualizing Heavy Fermion Confinement and Pauli-Limited Superconductivity in Layered CeCoIn5
András Gyenis, Benjamin E. Feldman, Mallika T. Randeria +4
Layered material structures play a key role in enhancing electron-electron interactions to create correlated metallic phases that can transform into unconventional superconducting…
Demonstration of efficient nonreciprocity in a microwave optomechanical circuit
G. A. Peterson, F. Lecocq, K. Cicak +3
The ability to engineer nonreciprocal interactions is an essential tool in modern communication technology as well as a powerful resource for building quantum networks. Aside from…
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…
