Optimal operation of a Josephson parametric amplifier for vacuum squeezing
M. Malnou, D. A. Palken, Leila R. Vale +2
A Josephson parametric amplifier (JPA) can create squeezed states of microwave light, lowering the noise associated with certain quantum measurements. We experimentally study how t…
Microwave SQUID Multiplexer demonstration for Cosmic Microwave Background Imagers
B. Dober, D. T. Becker, D. A. Bennett +10
Key performance characteristics are demonstrated for the microwave SQUID multiplexer (MUX) coupled to transition edge sensor (TES) bolometers that have been optimized for cosmic…
Widely tunable on-chip microwave circulator for superconducting quantum circuits
Benjamin J. Chapman, Eric I. Rosenthal, Joseph Kerckhoff +6
We report on the design and performance of an on-chip microwave circulator with a widely (GHz) tunable operation frequency. Non-reciprocity is created with a combination of frequen…
Single-sideband modulator for frequency domain multiplexing of superconducting qubit readout
Benjamin J. Chapman, Eric I. Rosenthal, Joseph Kerckhoff +3
We introduce and experimentally characterize a superconducting single-sideband modulator compatible with cryogenic microwave circuits, and propose its use for frequency domain mult…
Counting Near Infrared Photons with Microwave Kinetic Inductance Detectors
W. Guo, X. Liu, Y. Wang +8
We demonstrate photon counting at 1550 nm wavelength using microwave kinetic inductance detectors (MKIDs) made from TiN/Ti/TiN trilayer films with superconducting transition temper…
