abstract
Quantum simulations of lattice gauge theories for the foreseeable future will be hampered by limited resources. The historical success of improved lattice actions in classical simulations strongly suggests that Hamiltonians with improved discretization errors will reduce quantum resources, i.e. require $\gtrsim 2^d$ fewer qubits in quantum simulations for lattices with $d$ spatial dimensions. In this work, we consider $\mathcal{O}(a^2)$-improved Hamiltonians for pure gauge theories and design the corresponding quantum circuits for its real-time evolution in terms of primitive gates. An explicit demonstration for $\mathbb{Z}_2$ gauge theory is presented including exploratory tests using the ibm_perth device.

Obtaining continuum physics from dynamical simulations of Hamiltonian lattice gauge theories
The paper introduces the SBTE protocol, which treats approximate time evolution error as negligible once it is below statistical uncertainty, and shows this makes continuum-limit renormalization in lattice gauge theor...

Dynamical Local Tadpole-Improvement in Quantum Simulations of Gauge Theories
Tadpole improvement factors in real-time lattice gauge theory simulations are state- and time-dependent and should be updated self-consistently at each time step.
