Classical and quantum chaotic synchronization in coupled dissipative time crystals
Eliška Postavová, Gianluca Passarelli, Procolo Lucignano +1
We investigate the dynamics of two coherently coupled dissipative time crystals. In the classical mean-field limit of infinite spin length, we identify a regime of chaotic synchron…
Nonstabilizerness of a Boundary Time Crystal
Gianluca Passarelli, Angelo Russomanno, Procolo Lucignano
Boundary time crystals exhibit measurement-induced phase transitions in their steady-state entanglement, with critical behavior that depends on the particular unraveling of the Lin…
Noise Effects on Diabatic Quantum Annealing Protocols
Giulia Salatino, Maximilian Matzler, Annarita Scocco +2
Diabatic quantum annealing aims to mitigate the challenges posed by small energy gaps and decoherence in quantum optimization by exploiting nonadiabatic transitions. In this paper,…
Nonstabilizerness in the unitary and monitored quantum dynamics of XXZ-staggered and SYK models
Angelo Russomanno, Gianluca Passarelli, Davide Rossini +1
We consider the quantum-state-diffusion dynamics of the XXZ-staggered spin chain, also focusing on its noninteracting XX-staggered limit, and of the Sachdev-Ye-Kitaev (SYK) model.…
