It provides data structures and algorithms to compile quantum circuits and analyze fermionic Hamiltonians, with built-in support for converting between fermionic and qubit representations. The package depends on cirq-core for quantum circuit operations, numpy and scipy for numerical computation, sympy for symbolic algebra, networkx for graph operations, and h5py for data I/O, plus pubchempy and requests for chemistry data retrieval.\n\nThe package is designed for researchers and developers working on quantum algorithms for electronic structure problems. It integrates with external plugins for high-performance simulation (OpenFermion-FQE), circuit compilation (Forest-OpenFermion, SFOpenBoson), and classical electronic structure packages (Psi4, PySCF, DIRAC, Q-Chem). Installation is straightforward via pip, though some plugins require Mac or Linux.","worth_installing":"Yes. OpenFermion is actively maintained, has low install friction, carries no known vulnerabilities, and is licensed permissively. Install it if you are developing quantum algorithms for chemistry or fermionic systems. The main constraint is Python version (\u22653.10) and platform support for certain plugins (Mac/Linux preferred for electronic structure integration)."},"id":"openfermion","links":{"html":"https://skillfed.io/packages/openfermion","md":"https://skillfed.io/packages/openfermion.md","pypi":"https://pypi.org/project/openfermion/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-17","license_spdx":null,"license_treatment":"permissive","name":"openfermion","python_support":"supports_current","summary":"Package to compile and analyze quantum algorithms for simulating fermionic systems."},"popularity":{"monthly_downloads":210247,"position":9499,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"1.8.1"}
