IterativePhaseEstimation.estimate(unitary, state_preparation)

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.
