Suppressing relaxation in superconducting qubits by quasiparticle pumping

Simon Gustavsson, Fei Yan, Gianluigi Catelani +15

Dynamical error suppression techniques are commonly used to improve coherence in quantum systems. They reduce dephasing errors by applying control pulses designed to reverse errone…

The giant acoustic atom -- a single quantum system with a deterministic time delay

Lingzhen Guo, Arne Grimsmo, Anton Frisk Kockum +2

We investigate the quantum dynamics of a single transmon qubit coupled to surface acoustic waves (SAWs) via two distant connection points. Since the acoustic speed is five orders o…

Direct identification of dilute surface spins on AlO: Origin of flux noise in quantum circuits

S. E. de Graaf, A. A. Adamyan, T. Lindström +4

It is universally accepted that noise and decoherence affecting the performance of superconducting quantum circuits are consistent with the presence of spurious two-level systems (…

Experimental determination of irreversible entropy production in out-of-equilibrium mesoscopic quantum systems

M. Brunelli, L. Fusco, R. Landig +9

By making use of a recently proposed framework for the inference of thermodynamic irreversibility in bosonic quantum systems, we experimentally measure and characterize the entropy…
