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…
Origins of microwave losses in superconducting circuits made with silicon-on-insulator substrates
Simon Messelot, Nicolas Aparicio, Kazi Rafsanjani Amin +11
Silicon-on-insulator technology is widely used to fabricate silicon based devices, from advanced transistors to photonic circuits or nanomechanical systems. Integrating low loss su…
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…
Search for post-inflationary QCD axions with a quantum-limited tunable microwave receiver
Giosuè Sardo Infirri, David Alesini, Caterina Braggio +22
A search for cosmological axions has been performed by scanning a frequency region of MHz centered at about GHz, corresponding to an axion mass eV.…
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.…
