- IterativePhaseEstimation.estimate(unitary, state_preparation)[source]¶
Estimate the eigenphase of the input unitary and initial-state pair.
- প্যারামিটার
unitary (
QuantumCircuit
) -- The circuit representing the unitary operator whose eigenvalue (via phase) will be measured.state_preparation (
QuantumCircuit
) -- The circuit that prepares the state whose eigenphase will be measured. If this parameter is omitted, no preparation circuit will be run and input state will be the all-zero state in the computational basis.
