An ultracompact dilution refrigerator for fast quantum device characterization
Clment Geffroy, Dorian Nicolas, Eric Eyraud +10
Rapid thermal cycling is a central bottleneck in the development of superconducting quantum devices: conventional dilution refrigerators require cooldowns of a day or more and subs…
Quantitative calibration of a TWPA applied to an optomechanical platform
Alexandre Delattre, Ilya Golokolenov, Richard Pedurand +11
In the last decade, the microwave quantum electronics toolbox has been enriched with quantum-limited detection devices such as Traveling Wave Parametric Amplifiers (TWPAs). The ext…
Suppression of measurement-induced state transitions in cosÏ-coupling transmon readout
Cyril Mori, Francesca D Esposito, Alexandru Petrescu +12
Drive-induced unwanted state transitions (DUST) are limiting both for microwave readout and parametric operations of superconducting qubits. Among them, measurement-induced state t…
Gain compression in Josephson Traveling-Wave Parametric Amplifiers
Gwenael Le Gal, Guilliam Butseraen, Arpit Ranadive +6
Superconducting traveling-wave parametric amplifiers (TWPAs) are increasingly used in various applications, including quantum computing, quantum sensing, and dark matter detection.…
Investigating pump harmonics generation in a SNAIL-based Traveling Wave Parametric Amplifier
A. Yu. Levochkina, H. G. Ahmad, P. Mastrovito +16
Traveling Wave Parametric Amplifiers (TWPAs) are extensively employed in experiments involving weak microwave signals for their highly desirable quantum-limited and broadband chara…
