Three wave mixing vacuum squeezing generation in a SNAIL-based Traveling-Wave Parametric Amplifier with alternated flux polarity
Isita Chatterjee, Pegah Darvehi, Antonio Orsi +9
Recent demonstrations of squeezing generation using Traveling Wave Parametric Amplifiers (TWPAs) have opened the way for the application of broadband microwave squeezing in quantum…
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…
High-power readout of a transmon qubit using a nonlinear coupling
Cyril Mori, Vladimir Milchakov, Francesca D'Esposito +13
The field of superconducting qubits is constantly evolving with new circuit designs. However, when it comes to qubit readout, the use of simple transverse linear coupling remains o…
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.…
