MatrixExpectation

class MatrixExpectation

An Expectation converter which converts Operator measurements to be matrix-based so they can be evaluated by matrix multiplication.

Methods

MatrixExpectation.compute_variance(exp_op)	Compute the variance of the expectation estimator.
MatrixExpectation.convert(operator)	Accept an Operator and return a new Operator with the Pauli measurements replaced by Matrix based measurements.
