Add get_statetensor_to_sampled_expectation_func #24

Closed SamDuffield closed 2 years ago

SamDuffield commented 2 years ago

Currently only exact statetensor -> expectations are supported for quantum Hamiltonians.

We can implement the sampled (shots) version naively by

  1. sample bitstrings
  2. convert each bitstring to a statetensor (with all zeros except at the indices of the bitstrings)
  3. apply statetensor_to_expectation_func to each of these padded statetensors and average
