First-principles study of dispersive readout in circuit QED
Angela Riva, Prakritish Gogoi, Nicolas Gheeraert +4
The speed and fidelity of dispersive readout of superconducting qubits should improve by increasing the amplitude of the measurement drive. Experiments show, however, that beyond s…
The covariance matrix spectrum of correlated charge insulators reveals hidden connections to Coupled Cluster, Matrix Product, and Rokhsar-Kivelson states
Izak Snyman, Serge Florens
Charge ordering induced by strong short-range repulsion in itinerant fermion systems typically follows a two-sites alternation pattern. However, the covariance matrix spectrum of t…
Direct detection of down-converted photons spontaneously produced at a single Josephson junction
Dorian Fraudet, Izak Snyman, Denis M. Basko +7
We study spontaneous photon decay into multiple photons triggered by strong non-linearities in a superconducting quantum simulator of the boundary sine-Gordon impurity model. Previ…
Comment on "Absence versus Presence of Dissipative Quantum Phase Transition in Josephson Junctions''
Théo Sépulcre, Serge Florens, Izak Snyman
In a recent Letter [Phys. Rev. Lett. 129, 087001, (2022)], Masuki, Sudo, Oshikawa, and Ashida studied a Josephson junction, with Josephson energy and charging energy $E…
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…
Simulating realistic screening clouds around quantum impurities: role of spatial anisotropy and disorder
Maxime Debertolis, Izak Snyman, Serge Florens
Dynamical quantum impurities in metals induce electronic correlations in real space that are difficult to simulate due to their multi-scale nature, so that only s-wave scattering i…
