Query: Quantum simulation of the Schwinger model: A study of feasibility   We analyze some crucial questions regarding the practical feasibility of
quantum simulation for lattice gauge models. Our analysis focuses on two models
suitable for the quantum simulation of the Schwinger Hamiltonian, or QED in 1+1
dimensions, which we investigate numerically using tensor networks. In
particular, we explore the effect of representing the gauge degrees of freedom
with finite-dimensional systems and show that the results converge rapidly;
thus even with small dimensions it is possible to obtain a reasonable accuracy.
We also discuss the time scales required for the adiabatic preparation of the
interacting vacuum state and observe that for a suitable ramping of the
interaction the required time is almost insensitive to the system size and the
dimension of the physical systems. Finally, we address the possible presence of
noninvariant terms in the Hamiltonian that is realized in the experiment and
show that for low levels of noise it is still possible to achieve a good
precision for some ground-state observables, even if the gauge symmetry is not
exact in the implemented model.
