Noise-induced classical phases in optimally-unraveled random quantum circuits
Lorenzo Fioroni, Filippo Ferrari, Emanuele Tirrito
We study the classical simulability of open quantum dynamics using random Clifford circuits doped with non-Clifford phase rotations and subject to local noise. We unravel the dynam…
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…
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…
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…
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…
Dissipative Quantum Chaos unveiled by Stochastic Quantum Trajectories
Filippo Ferrari, Luca Gravina, Debbie Eeltink +3
We define quantum chaos and integrability in open quantum many-body systems as a dynamical property of single stochastic realizations, referred to as quantum trajectories. This def…
