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…
Nonperturbative signatures of fractons in the twisted multiflavor Schwinger Model
Pavel P. Popov, Valentin Kasper, Maciej Lewenstein +3
Gauge-field configurations with nontrivial topology have profound consequences for the physics of Abelian and non-Abelian gauge theories. Over time, arguments have been gathering f…
Symmetry verification for noisy quantum simulations of non-Abelian lattice gauge theories
Edoardo Ballini, Julius Mildenberger, Matteo M. Wauters +1
Non-Abelian gauge theories underlie our understanding of fundamental forces of modern physics. Simulating them on quantum hardware is an outstanding challenge in the rapidly evolvi…
Qudit-native measurement protocol for dynamical correlations using Hadamard tests
Pavel P. Popov, Kevin T. Geier, Valentin Kasper +2
Dynamical correlations reveal important out-of-equilibrium properties of the underlying quantum many-body system, yet they are notoriously difficult to measure in experiments. Whil…
Symmetry-protection Zeno phase transition in monitored lattice gauge theories
Matteo M. Wauters, Edoardo Ballini, Alberto Biella +1
Quantum measurements profoundly influence system dynamics. They lead to complex nonequilibrium phenomena like the quantum Zeno effect, and they can be used for mitigating errors in…
Quantum Simulation of non-Abelian Lattice Gauge Theories: a variational approach to
Emanuele Gaz, Pavel P. Popov, Guy Pardo +3
In this work, we address the problem of a resource-efficient formulation of non-Abelian LGTs by focusing on the difficulty of simulating fermionic degrees of freedom and the Hilber…
