This Strawberry Fields plugin library allows Strawberry Fields to interface with OpenFermion.



`Strawberry Fields `_ is a full-stack Python library for

designing, simulating, and optimizing continuous variable (CV) quantum optical circuits.



`OpenFermion `_ is an open source package for compiling and analyzing

quantum algorithms that simulate fermionic systems.



Features

========



* Construct bosonic Hamiltonians in OpenFermion, and apply the resulting time propagation using  a CV quantum circuit.



* Calculates the time-evolution unitary exactly for Gaussian Hamiltonians – these can then be decomposed into the base CV gate set of Strawberry Fields using the Bloch-Messiah decomposition.



* Particular non-Gaussian gate decompositions, using the Trotter formula, are also supported, including Bose-Hubbard Hamiltonians.



* The Hamiltonians submodule contains important OpenFermion-compatible CV Hamiltonians, including those corresponding to the gate set used in Strawberry Fields.



To get started, please see the online `documentation `_
