Global and nonlocal magic of quantum many-body scars
Lukas Ebner, Giovanni Cataldi, Kaidi Xu +2
Nonergodic features of chaotic quantum many-body systems are commonly characterized through local observables, fidelity, and entanglement entropy. Here, using global and nonlocal m…
Quantum Resources in Disorder-Free Localization Dynamics of Gauge Theories
Devendra Singh Bhakuni, Giovanni Cataldi, Jad C. Halimeh +1
Quantum-state complexity diagnostics provide valuable insight into many-body dynamics, information scrambling, and quantum computation. Here, we investigate the real-time dynamics…
Digital quantum simulation of lattice fermion theories with local encoding
Marco Ballarin, Giovanni Cataldi, Giuseppe Magnifico +5
We numerically analyze the feasibility of a platform-neutral, general strategy to perform quantum simulations of fermionic lattice field theories under open boundary conditions. Th…
Hilbert curve vs Hilbert space: exploiting fractal 2D covering to increase tensor network efficiency
Giovanni Cataldi, Ashkan Abedi, Giuseppe Magnifico +4
We present a novel mapping for studying 2D many-body quantum systems by solving an effective, one-dimensional long-range model in place of the original two-dimensional short-range…
