Long-lasting Topological Entanglement in a Monitored Rashba Nanowire
Emanuele Guida, Giulia Salatino, Gianluca Passarelli +2
We study the topological properties of a monitored Rashba chain along quantum-jump trajectories, investigating the persistence of the initial topological value of the disconnected…
Range-controlled entanglement in Lindbladian skin states of monitored fermions
Gianluca Passarelli, Angelo Russomanno, Davide Rossini +1
Reservoir engineering can stabilize states inaccessible to unitary dynamics. Directed particle-conserving dissipation creates Lindbladian skin states, where Pauli exclusion turns e…
Operator delocalization in disordered spin chains via exact MPO marginals
Jonnathan Pineda, Mario Collura, Gianluca Passarelli +3
We investigate operator delocalization in disordered one-dimensional spin chains by introducing -- besides the already known operator mass -- a complementary measure of operator co…
Nonadiabatic Self-Healing of Trotter Errors in Digitized Counterdiabatic Dynamics
Mara Vizzuso, Gianluca Passarelli, Giovanni Cantele +3
Trotter errors in digitized quantum dynamics arise from approximating time-ordered evolution under noncommuting Hamiltonian terms with a product formula. In the adiabatic regime, s…
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.…
