X-parameter based design and simulation of Josephson traveling-wave parametric amplifiers for quantum computing applications
Kaidong Peng, Rick Poore, Philip Krantz +2
We present an efficient, accurate, and comprehensive analysis framework for generic, multi-port nonlinear parametric circuits, in the presence of dissipation from lossy circuit com…
Microwave calibration of qubit drive line components at millikelvin temperatures
Slawomir Simbierowicz, Volodymyr Y. Monarkha, Suren Singh +3
Systematic errors in qubit state preparation arise due to non-idealities in the qubit control lines such as impedance mismatch. Using a data-based methodology of short-open-load ca…
Broadband Squeezed Microwaves and Amplification with a Josephson Traveling-Wave Parametric Amplifier
Jack Y. Qiu, Arne Grimsmo, Kaidong Peng +16
Squeezing of the electromagnetic vacuum is an essential metrological technique used to reduce quantum noise in applications spanning gravitational wave detection, biological micros…
Engineering Framework for Optimizing Superconducting Qubit Designs
Fei Yan, Youngkyu Sung, Philip Krantz +6
Superconducting quantum technologies require qubit systems whose properties meet several often conflicting requirements, such as long coherence times and high anharmonicity. Here,…
Generating Spatially Entangled Itinerant Photons with Waveguide Quantum Electrodynamics
Bharath Kannan, Daniel Campbell, Francisca Vasconcelos +10
Realizing a fully connected network of quantum processors requires the ability to distribute quantum entanglement. For distant processing nodes, this can be achieved by generating,…
Multi-level Quantum Noise Spectroscopy
Youngkyu Sung, Antti Vepsäläinen, Jochen Braumüller +14
System noise identification is crucial to the engineering of robust quantum systems. Although existing quantum noise spectroscopy (QNS) protocols measure an aggregate amount of noi…
