Description

@srwhite59 suggested an interesting idea for implementing n-point correlators as a product of MPOs, one for each operator, which captures the logic of placing the operator in a superposition of each site it is being measured on. I think it could simplify the implementation of ITensorCorrelators.jl and also make it easier to generalize that package to tree tensor networks or even loopy tensor networks.

Research direction

Start by reviewing the existing ITensorCorrelators.jl implementation and how this repository represents MPOs. The issue proposes n-point correlators as a product of one MPO per operator, with possible future support for tree or loopy tensor networks; completion criteria and relevant tests are not specified.
