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.
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".
