Add implementation of Estimator primitive to ffsim.qiskit #174

Open kevinsung opened 3 months ago

Implementation of the Qiskit Estimator interface that supports gates from the ffsim.qiskit module.

Actually, this may not be straightforward because the Estimator interface accepts Pauli observables, not fermionic ones.

One possibility is to map the observable to a molecular Hamiltonian and then measure in the bases defined by a low-rank decomposition.
