Creating official release from March 6th v1.0.1 release of OpenFermion associated with commit ( c22551fbb8f7965c0d3fd0fc119ff2f8b569917a).

v1.0

3 years ago

This release is for the stable 1.0 version of OpenFermion. Significant changes from the 0.11 release have been made. The most notable changes are listed below.

Features:

MajoranaOperator <-> FermionOperator with Jordan-Wigner + Bravyi-Kitaev options, get_majorana acts like get_fermion operator. Is_contextual for confirming if a Hamiltonian is contextual SymbolicOperator coefficients are sympy.Expr objects Partitioning schemes for measuring fermionic 1- and 2-RDMs Functionality for the Hartree-Fock project Spatial -> spin-orbital integrals Extended RPA Constructing a pure 2-body (reduced Hamiltonian) from 1-body and 2-body InteractionOperator. Construct antisymmeterized 2-electron integrals + coulomb + exchange matrices Verified phase estimation utilities

Organization:

Merging of OpenFermion-Cirq into OpenFermion Reorganize package (#620) (new submodules: chem, linalg, circuits, functionals, transforms) Sample data is integrated with package for testing. Reorganize utils Deprecation of Readthedocs as the documentation host. Docs are now generator by tensorflow-docs and hosted at https://quantumai.google/openfermion
