Transmon-qubit readout using in-situ bifurcation amplification in the mesoscopic regime
R. Dassonneville, T. Ramos, V. Milchakov +8
We demonstrate a transmon qubit readout based on the nonlinear response to a drive of polaritonic meters in-situ coupled to the qubit. Inside a 3D readout cavity, we place a transm…
Revealing the finite-frequency response of a bosonic quantum impurity
Sébastien Léger, Théo Sépulcre, Dorian Fraudet +7
Quantum impurities are ubiquitous in condensed matter physics and constitute the most stripped-down realization of many-body problems. While measuring their finite-frequency respon…
Evidence of dual Shapiro steps in a Josephson junctions array
Nicolò Crescini, Samuel Cailleaux, Wiebke Guichard +4
The modern primary voltage standard is based on the AC Josephson effect and the ensuing Shapiro steps, where a microwave tone applied to a Josephson junction yields a constant volt…
Observation of two-mode squeezing in a traveling wave parametric amplifier
Martina Esposito, Arpit Ranadive, Luca Planat +9
Traveling wave parametric amplifiers (TWPAs) have recently emerged as essential tools for broadband near quantum-limited amplification. However, their use to generate microwave qua…
Kerr reversal in Josephson meta-material and traveling wave parametric amplification
Arpit Ranadive, Martina Esposito, Luca Planat +5
Josephson meta-materials have recently emerged as very promising platform for superconducting quantum science and technologies. Their distinguishing potential resides in ability to…
Highly transparent contacts to the 1D hole gas in ultra-scaled Ge/Si core/shell nanowires
Masiar Sistani, Jovian Delaforce, Roman Kramer +10
Semiconductor-superconductor hybrid systems have outstanding potential for emerging high-performance nanoelectronics and quantum devices. However, critical to their successful appl…
