TPBGroupedWeightedPauliOperator.construct_evaluation_circuit¶
- TPBGroupedWeightedPauliOperator.construct_evaluation_circuit(wave_function, statevector_mode, qr=None, cr=None, use_simulator_snapshot_mode=False, circuit_name_prefix='')¶
Construct the circuits for evaluation, which calculating the expectation <psi|H|psi>.
At statevector mode: to simplify the computation, we do not build the whole circuit for <psi|H|psi>, instead of that we construct an individual circuit <psi|, and a bundle circuit for H|psi>
- Parameters
wave_function (QuantumCircuit) – the quantum circuit.
statevector_mode (bool) – indicate which type of simulator are going to use.
qr (QuantumRegister, optional) – the quantum register associated with the input_circuit
cr (ClassicalRegister, optional) – the classical register associated with the input_circuit
use_simulator_snapshot_mode (bool, optional) – if aer_provider is used, we can do faster evaluation for pauli mode on statevector simulation
circuit_name_prefix (str, optional) – a prefix of circuit name
- Returns
- a list of quantum circuits and each circuit with a unique name:
circuit_name_prefix + Pauli string
- Return type
list[QuantumCircuit]
- Raises
