Determine the difference between the exact generator of unitary
openfermion.circuits.error_operator( terms, series_order=2 )
evolution and the approximate generator given by Trotter-Suzuki to the given order.
||a list of QubitTerms in the Hamiltonian to be simulated.|
||the order at which to compute the BCH expansion. Only the second order formula is currently implemented (corresponding to Equation 9 of the paper).|
|The difference between the true and effective generators of time evolution for a single Trotter step.|
Notes: follows Equation 9 of Poulin et al.'s work in "The Trotter Step Size Required for Accurate Quantum Simulation of Quantum Chemistry".
