- IterativePhaseEstimation.construct_circuit(unitary, state_preparation, k, omega=0.0, measurement=False)[Quellcode]¶
Construct the kth iteration Quantum Phase Estimation circuit.
For details of parameters, see Fig. 2 in https://arxiv.org/pdf/quant-ph/0610214.pdf.
- Parameter
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.k (
int) – the iteration idx.omega (
float) – the feedback angle.measurement (
bool) – Boolean flag to indicate if measurement should be included in the circuit.
