Suppression of measurement-induced state transitions in cosϕ-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…

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…
