Dissipation-enhanced scrambling in the SYK model coupled to a lossy cavity
Pietro Pelliconi, Bastien Lapierre, Shinsei Ryu
We study the Yukawa-Sachdev-Ye-Kitaev model, a disordered model of Majorana fermions and bosons in which the bosons are linearly coupled to independent realizations of S…
Emergent Self-Similar Quantum Revivals in Spiral Drives
Xin-Chi Zhou, Liang-Hong Mo, Hongzheng Zhao +1
We uncover a distinct form of nonequilibrium temporal order: self-similar quantum revivals in a many-body system driven by quasiperiodic spiral kicks, where the system recurrently…
Observing Conformal Floquet Dynamics on a Digital Quantum Processor
Liang-Hong Mo, Bastien Lapierre, Qiang Miao
Quantum simulations are traditionally confined to exploring dynamics starting from unentangled or low-entanglement states due to severe bottlenecks in protocol design, hardware per…
Bootstrapping Symmetries in Quantum Many-Body Systems from the Cross Spectral Form Factor
Chen Bai, Zihan Zhou, Bastien Lapierre +1
Symmetries play a central role in quantum many-body physics, yet uncovering them systematically remains challenging. We introduce a bootstrap framework to reconstruct the represent…
Observing quantum many-body dynamics in emergent curved spacetime using programmable quantum processors
Brendan Rhyno, Bastien Lapierre, Smitha Vishveshwara +2
We digitally simulate quantum many-body dynamics in emergent curved backgrounds using 80 superconducting qubits on IBM Heron processors. By engineering spatially varying couplings…
Local-to-Global Entanglement Dynamics by Periodically Driving Impurities
Zhi-Xing Lin, Abhinav Prem, Shinsei Ryu +1
We study the entanglement dynamics of one-dimensional fermionic chains subject to a local Floquet drive of a two-site impurity, and uncover a sharp transition in the entanglement d…
Entanglement transitions in structured and random nonunitary Gaussian circuits
Bastien Lapierre, Liang-Hong Mo, Shinsei Ryu
We study measurement-induced phase transitions in quantum circuits consisting of kicked Ising models with postselected weak measurements, whose dynamics can be mapped onto a classi…
