Driven-dissipative stabilization of Floquet-Laughlin states in the bosonic Harper-Hofstadter-Hubbard model is achieved by coupling to tuneable artificial environments realized with leaky cavity modes.
Multimode strong coupling in circuit QED lattices produces emergent band gaps, lifted degeneracies, and a four-wave mixing process dominated by localized flat-band modes.
A SQUID-array Josephson parametric amplifier achieves near-quantum-limited 20 dB gain over ~50 MHz bandwidth, with its complex gain spectra analytically reproduced by adding Fabry-Pérot interference to a quantum input-output model.
Microscopic unitary simulation of circuit QED readout shows qubit T1 drops with increasing drive amplitude when a Purcell notch filter is at the qubit frequency, exposing qualitative defects in Lindblad master equations.
A dual-function TED circuit emits and detects single microwave photons with 60% observed efficiency and 95% inferred detection efficiency using a double transmon coupler.
A parity-violating Kerr parametric oscillator exhibits doubly-degenerate levels via antiunitary symmetry, showing spontaneous symmetry breaking is possible without parity protection.
Topological data analysis on scattering spectra extracts phase features and differentiates Dyson ensembles in light-matter systems despite noise and background resonances.
In the open coupled-top Dicke model, photon loss induces spontaneous synchronization and two distinct dissipative quantum scars, one protected with persistent revivals and one showing slow decay linked to chaos-assisted tunneling for small spins.
A driven two-level system generates distributable entanglement via Mollow sidebands, but near-maximal remote entanglement stabilization requires added filter cavities and optimized driving parameters explained by an effective two-mode squeezing model.
In an N-qubit network with one conserved excitation, a single transition amplitude determines positivity and complete positivity of subsystem propagators, links them to excitation flow and Fisher information, and reveals an unvisited band of states inside the positivity domain.
Graphene Josephson junctions exhibit gate-, temperature-, and bias-tunable Kerr nonlinearity with coefficients ranging from 300 kHz to 1.2 MHz.
