Suppressing Cavity Frequency Noise Using a Kerr Nonlinearity
J. P. van Soest, S. Meilof, G. L. Bhai +3
Resonance-frequency fluctuations can limit the sensitivity and stability of superconducting microwave cavities used for qubit readout, optomechanical displacement sensing, and magn…
Experimental realization of a transmon qubit
Erwan Roverc'h, Alvise Borgognoni, Marius Villiers +7
Superconducting circuits with embedded symmetries are good candidates to robustly protect quantum information from dominant error channels. The qubit, consisting of an i…
Dissipating quartets of excitations in a superconducting circuit
Aron Vanselow, Brieuc Beauseigneur, Louis Lattier +5
Over the past decade, autonomous stabilization of bosonic qubits has emerged as a promising approach for hardware-efficient protection of quantum information. However, applying the…
Two-tone spectroscopy of high-frequency quantum circuits with a Josephson emitter
A. Peugeot, H. Riechert, S. Annabi +7
We perform two-tone spectroscopy on quantum circuits, where high-frequency radiation is generated by a voltage-biased superconductor-normal-superconductor Josephson junction and de…
