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…

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…

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…

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…
