Photonic Analog Quantum Simulation of (1+1)-Dimensional Lattice Gauge Theory with Dynamical Matter

Nathan R. Gonzalez, Thea Budde, Klemen Kersic +5

We propose a photonic scheme for analog quantum simulation of a Lattice Gauge Theory (LGT) with dynamical matter based on the Jaynes-Cummings-Hubbard (JCH) model. Here, an a…

Hilbert Space Fragmentation and Gauge Symmetry

Thea Budde, Marina Kristć Marinković, Joao C. Pinto Barros

The Hamiltonian formulation of lattice gauge theories plays a central role in quantum simulations of gauge theories, and understanding their spectrum and other properties is expect…

Hilbert Space Fragmentation from Generalized Symmetries

Thea Budde, Marina Kristć Marinković, Joao C. Pinto Barros

Hilbert space fragmentation refers to exponential growth in the number of dynamically disconnected Krylov sectors with system size. It is taken as evidence of ergodicity breaking,…

Spectrum-Generating Algebra in Higher Dimensional Gauge Theories

Thea Budde, Jiangjing Dong, Marina Krstić Marinković +1

Non-equilibrium properties of strongly interacting gauge theories are often intractable with classical simulation methods. Due to recent developments of quantum simulations, studie…

The Lattice Schwinger Model and Its Quantum Simulation

Joao C. Pinto Barros, Pierpaolo Fontana, Pasquale Sodano +1

In this chapter we review results on the lattice Schwinger model. In par-ticular, we show how the effect of the anomaly is reproduced on the lattice. We connect these results to re…

Adiabatic state preparation for digital quantum simulations of QED in 1 + 1D

Matteo D'Anna, Marina Krstic Marinkovic, Joao C. Pinto Barros

Quantum electrodynamics in 1 + 1D (QED2) shares intriguing properties with QCD, including confinement, string breaking, and interesting phase diagram when the non-trivial topologic…
