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…
Quantum Resources in Non-Abelian Lattice Gauge Theories: Nonstabilizerness, Multipartite Entanglement, and Fermionic Non-Gaussianity
Gopal Chandra Santra, Julius Mildenberger, Edoardo Ballini +3
Lattice gauge theories (LGTs) represent one of the most ambitious goals of quantum simulation. From a practical implementation perspective, non-Abelian theories present significant…
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…
A Monte Carlo Tree Search approach to QAOA: finding a needle in the haystack
Andoni Agirre, Evert Van Nieuwenburg, Matteo M. Wauters
The search for quantum algorithms to tackle classical combinatorial optimization problems has long been one of the most attractive yet challenging research topics in quantum comput…
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…
