Numerical study of computational cost of maintaining adiabaticity for long paths
Thomas D. Cohen, Hyunwoo Oh, Veronica Wang
Recent work argued that the scaling of a dimensionless quantity with path length is a better proxy for quantifying the scaling of the computational cost of maintaining adiaba…

Corrections to adiabatic behavior for long paths
Thomas D. Cohen, Hyunwoo Oh
The cost and the error of the adiabatic theorem for preparing the final eigenstate are discussed in terms of path length. Previous studies in terms of the norm of the Hamiltonian a…

Zeno Effect Suppression of Gauge Drift in Quantum Simulations
Carter Ball, Thomas D. Cohen
Quantum simulation of lattice gauge theories is a promising tool for the study of many complicated problems including ones with real-time dynamics. For gauge theories, however, the…
