SFOpenBoson 0.3.0

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
