openfermion.circuits.trotter_steps_required

Determine the number of Trotter steps for accurate simulation.

Main aliases

openfermion.circuits.trotter_steps_required(
    trotter_error_bound, time, energy_precision
)

Args
`trotter_error_bound`	`float` Upper bound on Trotter error in the state of interest.
`time`	`float` The total simulation time.
`energy_precision`	`float` Acceptable shift in state energy.

Args

trotter_error_bound

float

Upper bound on Trotter error in the state of interest.

time

float

The total simulation time.

energy_precision

float

Acceptable shift in state energy.

Returns
The integer minimum number of Trotter steps required for simulation to the desired precision.

Notes
The number of Trotter steps required is an upper bound on the true requirement, which may be lower.
