Engineering of non-Hermitian interactions in digital qudit quantum simulators
Matteo M. Wauters, Paolo Boschetto, Edoardo Ballini +2
Non-Hermitian Hamiltonians are a fascinating class of many-body models that describe the effective dynamics of quantum systems interacting with the environment through particle, en…
Theory of the correlated quantum Zeno effect in a monitored qubit dimer
Severino Zeni, Gobinda Chakraborty, Alessandro Romito +1
We theoretically investigate the stochastic dynamics of two qubits subject to one- and two-site correlated continuous weak measurements. When measurements dominate over the local u…
Quantum jump correlations in long-range dissipative spin systems via cluster and cumulant expansions
Giulia Salatino, Anna Delmonte, Zejian Li +2
We characterize nonequilibrium phases in long-range dissipative spin systems through the statistical properties of quantum jump trajectories. While the average dynamics governed by…
Dispersive detection of single microwave photons with quantum dots
Stephanie Matern, Alberto Biella, Pasquale Scarlino +2
Within a circuit quantum electrodynamics architecture, we theoretically investigate the detection of a single propagating microwave photon traveling through a resonant microwave ca…
Many-body theory of false vacuum decay in quantum spin chains
Christian Johansen, Alessio Recati, Iacopo Carusotto +1
In this work we theoretically investigate the false vacuum decay process in a ferromagnetic quantum spin-1/2 chain. We develop a many-body theory describing the nucleation and the…
Dissipative quantum North-East-Center model: steady-state phase diagram, universality and nonergodic dynamics
Pietro Brighi, Alberto Biella
In this work we study the dissipative quantum North-East-Center (NEC) model: a two-dimensional spin-1/2 lattice subject to chiral, kinetically constrained dissipation and coherent…
