Quantum back-action of variable-strength measurement
M. Hatridge, S. Shankar, M. Mirrahimi +9
Measuring a quantum system can randomly perturb its state. The strength and nature of this back-action depends on the quantity which is measured. In a partial measurement performed…
Three-wave mixing with three incoming waves: Signal-Idler Coherent Cancellation and Gain Enhancement in a Parametric Amplifier
Flavius Schackert, Ananda Roy, Michael Hatridge +2
Coherent, purely-dispersive three-wave mixing systems in optics and superconducting microwave circuits can be operated as parametric amplifiers, generating from a pump wave at one…
Full coherent frequency conversion between two microwave propagating modes
Baleegh Abdo, Katrina Sliwa, Flavius Schackert +5
We demonstrate full frequency conversion in the microwave domain using a Josephson three-wave mixing device pumped at the difference between the frequencies of its fundamental eige…
Josephson Amplifier for Qubit Readout
Baleegh Abdo, Flavius Schackert, Michael Hatridge +2
We report on measurements of a Josephson amplifier (J-amp) suitable for quantum-state qubit readout in the microwave domain. It consists of two microstrip resonators which intersec…
Two-mode Correlation of Microwave Quantum Noise Generated by Parametric Down-Conversion
N. Bergeal, F. Schackert, L. Frunzio +1
In this letter, we report the observation of the correlation between two modes of microwave radiation resulting from the amplification of quantum noise by the Josephson Parametric…
Phase preserving amplification near the quantum limit with a Josephson Ring Modulator
N. Bergeal, F. Schackert, M. Metcalfe +7
Recent progress in solid state quantum information processing has stimulated the search for ultra-low-noise amplifiers and frequency converters in the microwave frequency range, wh…
