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

Strawberry Fields <http://github.com/XanaduAI/strawberryfields>_ is a full-stack Python library for designing, simulating, and optimizing continuous variable (CV) quantum optical circuits.

OpenFermion <http://openfermion.org>_ 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 <https://sfopenboson.readthedocs.io>_

Installation

Installation of SFOpenBoson, as well as all required Python packages mentioned above, can be done using pip: ::
