Suppressing chaos with mixed superconducting qubit devices

Ben Blain, Giampiero Marchegiani, Luigi Amico +1

In quantum information processing, a tension between two different tasks occurs: while qubits' states can be preserved by isolating them, quantum gates can be realized only through…

Synthetic fractional flux quanta in a ring of superconducting qubits

Luca Chirolli, Juan Polo, Gianluigi Catelani +1

A ring of capacitively coupled transmons threaded by a synthetic magnetic field is studied as a realization of a strongly interacting bosonic system. The synthetic flux is imparted…

Rapid on-demand generation of thermal states in superconducting quantum circuits

Timm Fabian Mörstedt, Wallace Santos Teixeira, Arto Viitanen +13

We experimentally demonstrate the fast generation of thermal states of a transmon using a single-junction quantum-circuit refrigerator (QCR) as an in-situ-tunable environment. Thro…

Modeling phonon-mediated quasiparticle poisoning in superconducting qubit arrays

Eric Yelton, Clayton P. Larson, Vito Iaia +8

Correlated errors caused by ionizing radiation impacting superconducting qubit chips are problematic for quantum error correction. Such impacts generate quasiparticle (QP) excitati…

Observation of Josephson Harmonics in Tunnel Junctions

Dennis Willsch, Dennis Rieger, Patrick Winkel +27

Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices. State…

Nonequilibrium quasiparticle distribution in superconducting resonators: analytical approach

P. B. Fischer, G. Catelani

In the superconducting state, the presence of a finite gap in the excitation spectrum implies that the number of excitations (quasiparticles) is exponentially small at temperatures…
