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…
Non-degenerate parametric amplifiers based on dispersion engineered Josephson junction arrays
Patrick Winkel, Ivan Takmakov, Dennis Rieger +12
Determining the state of a qubit on a timescale much shorter than its relaxation time is an essential requirement for quantum information processing. With the aid of a new type of…
