__init__(*args, **kwargs)

calculate_expectation_value(pauli_sum: HermitianPauliSum, measurement: QuantumMeasurement) → ExpectationValue

Calculate the expectation value of the given pauli strings from the measurement.

Parameters:

• pauli_sum (HermitianPauliSum) – The Pauli sum to calculate the expectation value for.

• measurement (QuantumMeasurement) – The measurement results.

Return type:

ExpectationValue

get_diagonalizing_circuit(num_qubits: int) → Circuit

Get the diagonalizing circuit for the given number of qubits.

Parameters:

num_qubits (int) – The number of qubits in the circuit.

Return type:

Circuit

is_compatible_with(other: PauliString) → bool

Check if compatible with other.

Parameters:

other (PauliString)

Return type:

bool

is_diagonal() → bool

Check if the basis is diagonal.

Return type:

bool
