squlearn.util.optree.OpTreeExpectationValue

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

Leaf of the OpTree that represents an expectation value of a circuit and an operator.

Parameters:

• circuit (Union[OpTreeLeafCircuit, QuantumCircuit]) – The circuit in the expectation value.

• operator (Union[OpTreeLeafOperator, SparsePauliOp]) – The operator in the expectation value.
