Q-Chem provides a capability to dump all quantities required for interfacing with the OpenFermion package507 (and similar softwares) for quantum computation. This feature is controlled by the PRINT_QIS keyword. Setting it to TRUE activates the dump: Fock operator, two-electron integrals, and energies of molecular orbitals are saved in separate files in the home directory. OpenFermion (development version, soon to be checked into official github repository) contains an import module, which understands how to read these files, and several unit tests. Example 7.10.30 illustrates this capability for water molecule.
Note: Core should not be frozen.
