Dissipation-induced Sachdev-Ye-Kitaev physics in many-body cavity quantum electrodynamics
Pietro Pacchioni, Filippo Ferrari, Vincenzo Savona +1
We show that cavity quantum electrodynamics (QED) devices can realize dissipative Sachdev-Ye-Kitaev (SYK) universality, a paradigmatic setting for quantum chaos in open many-body s…
Dissipative phase transitions and chaos in two-photon driven quantum optomechanics
Giovanni Bragadin, Filippo Ferrari, Lorenzo Fioroni +4
We investigate nonequilibrium criticality and chaos in a two-photon-driven optomechanical system. The parametric drive preserves a discrete symmetry of the optical f…
Controlling many-body quantum chaos in a dissipative optical cavity
Filippo Ferrari, Francesca Orsi, Ekaterina Fedotova +4
Cavity quantum electrodynamics (QED) with ultracold fermions provides a promising platform for realizing many-body quantum chaos through disordered, photon-mediated long-range inte…
Bit flips are erasures in dissipative cat qubits
Filippo Ferrari, Joachim Cohen, Vincenzo Savona +1
Autonomous quantum error correction (QEC) stabilizes a logical manifold through dissipative events that emit into output channels, which are typically accessible to measurement. Th…
Density Wave Ordering with Disordered Ultracold Fermions in Optical Cavities
Óscar Rios Alves, Filippo Ferrari, Lorenzo Fioroni +2
We investigate the interplay between cavity-induced density-wave ordering and controllable disorder in a trapped two-dimensional gas of ultracold fermions. The atoms are dispersive…
Bit flips, saturation, and quantum chaos in dissipative cat qubits
Filippo Ferrari, Joachim Cohen, Vincenzo Savona +1
Bosonic cat qubits promise hardware-efficient quantum error correction because their logical bit-flip rate is exponentially suppressed with the photon number of the cat state. Howe…
Floquet Dissipative Phase Transitions
Alberto Mercurio, Vincenzo Macrì, Filippo Ferrari +2
Dissipative phase transitions (DPTs) are traditionally characterized through the spectrum of a time-independent Liouvillian superoperator. However, this definition does not apply t…
Superstrong Dynamics and Directional Emission of a Giant Atom in a Structured Bath
Vincent Jouanny, Léo Peyruchat, Marco Scigliuzzo +8
Quantum emitters coupled to waveguides with nonlinear dispersion show rich quantum dynamics with the promise of implementing non-trivial non-Markovian quantum models. Recent advanc…
Chaos and quantum regimes in -photon driven, dissipative bosonic chains
Leo Kruglikov, Filippo Ferrari, Vincenzo Savona
We investigate the steady-state dynamical regimes of boundary-driven, dissipative bosonic chains subjected to -photon drives. Using the truncated Wigner approximation, we explor…
Chaos and thermalization in open quantum systems
Filippo Ferrari, Vincenzo Savona, Fabrizio Minganti
The eigenstate thermalization hypothesis (ETH) provides a cornerstone for understanding thermalization in isolated quantum systems, linking quantum chaos with statistical mechanics…
QuantumToolbox.jl: An efficient Julia framework for simulating open quantum systems
Alberto Mercurio, Yi-Te Huang, Li-Xun Cai +3
We present QuantumToolboxjl, an open-source Julia package for simulating open quantum systems. Designed with a syntax familiar to users of QuTiP (Quantum Toolbox in Python), it…
Renormalization and Low-Energy Effective Models in Cavity and Circuit QED
Daniele Lamberto, Alberto Mercurio, Omar Di Stefano +2
The quantum Rabi model (QRM) is a cornerstone in the study of light-matter interactions within cavity and circuit quantum electrodynamics (QED). It effectively captures the dynamic…
Chiral cat code: Enhanced error correction induced by higher-order nonlinearities
Adrià Labay-Mora, Alberto Mercurio, Vincenzo Savona +2
We introduce a Schrödinger chiral cat qubit, a novel bosonic quantum code generalizing Kerr cat qubits that exploits higher-order nonlinearities. Compared to a standard Kerr cat, t…
Chaotic and quantum dynamics in driven-dissipative bosonic chains
Filippo Ferrari, Fabrizio Minganti, Camille Aron +1
Thermalization in quantum many-body systems typically unfolds over timescales governed by intrinsic relaxation mechanisms. Yet, its spatial aspect is less understood. We investigat…
Landau-Zener without a Qubit: Unveiling Multiphoton Interference, Synthetic Floquet Dimensions, and Dissipative Quantum Chaos
Leo Peyruchat, Fabrizio Minganti, Marco Scigliuzzo +5
Landau-Zener-Stückelberg-Majorana (LZSM) interference occurs when qubit parameters are periodically modulated across avoided level crossings. We explore this phenomenon in nonlinea…

Guillaume Beaulieu, Fabrizio Minganti, Simone Frasca +4
In open quantum systems, first- and second-order dissipative phase transitions (DPTs) can emerge in the thermodynamic limit from the competition between unitary evolution, driving…
