Rectangular gkp #668

Open elib20 opened 2 years ago

elib20 commented 2 years ago

Context: Currently, strawberryfields only supports square lattice GKP states. The simplest more general type of GKP states are rectangular lattice GKP states (instead of peak spacing by sqrt(pi) in q quadrature, it's sqrt(alpha*sqrt(pi)). This allows for, e.g. GKP sensor states.

Description of the Change: Adds the ability to initialize rectangular GKP states to the bosonic and fock backends.

Benefits: Wider class of states to simulate.

Possible Drawbacks:
