Bases:
OptionalMultiTarget
,Observable
Expectation of specified targets and observable as requested result. If no targets are specified, the observable must only operate on 1 qubit and it will be applied to all qubits in parallel. Otherwise, the number of specified targets must be equivalent to the number of qubits the observable can be applied to.
- type
The result type. default = “expectation”. (type) is optional. This should be unique among all result types.
- Type:
str
- targets
The target qubits. This is a list of int >= 0.
- Type:
Optional[List[int]]
- observable
A list with at least one item and items are strings matching the observable regex or a two dimensional hermitian matrix with complex entries. Each complex number is represented using a List[float] of size 2, with element[0] being the real part and element[1] imaginary. inf, -inf, and NaN are not allowable inputs for the element.
- Type:
List[Union[str, List[List[List[float]]]]
Examples
>>> Expectation(targets=[1], observable=["x"])
