Description

Given a tensor of PauliSums, one may want to repeatedly measure these operators. This would be a generalization of the Sample layer, which is implicitly performing this calculation for a tensor of single qubit Z pauli sums. Currently, only the Expectation layer ingests operators.

Contributor guide

Research direction
Study the implementation of the Sample layer and understand how it measures single qubit Z PauliSums. Then design a generalized layer that can handle tensors of arbitrary PauliSums.
