squlearn.util.optree.OpTreeMeasuredOperator

class squlearn.util.optree.OpTreeMeasuredOperator(circuit: OpTreeCircuit | QuantumCircuit, operator: OpTreeOperator | SparsePauliOp)

Leaf of the OpTree that represents an measurement.

The circuit in the class represents the circuit that is measured for the given operator.

copy()

Function for copying a OpTreeLeafMeasuredOperator object.

measure_circuit(circuit: QuantumCircuit | OpTreeCircuit) → OpTreeExpectationValue

Applies the measurement of the leaf to the circuit and returns an expectation value.

Parameters:

circuit (Union[QuantumCircuit, OpTreeLeafCircuit]) – The circuit that is measured.

Returns:

The expectation value leaf with the measured circuit.

Return type:

OpTreeLeafExpectationValue
