openfermion.circuits.error_operator

Determine the difference between the exact generator of unitary evolution and the approximate generator given by Trotter-Suzuki to the given order.

Main aliases

openfermion.circuits.error_operator(
    terms, series_order=2
)

Args
`terms`	a list of QubitTerms in the Hamiltonian to be simulated.
`series_order`	the order at which to compute the BCH expansion. Only the second order formula is currently implemented (corresponding to Equation 9 of the paper).

Returns
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".
