We present ffsim, an open-source software library for simulating fermionic quantum circuits that conserve particle number and the Z component of spin. This category includes many quantum circuits used for quantum chemistry simulations. By exploiting the symmetries and using specialized algorithms, ffsim can simulate these circuits much faster than a generic quantum circuit simulator. The source code of ffsim is available at https://github.com/qiskit-community/ffsim.
Kevin J. Sung earned his PhD in computer science from the University of Michigan in 2020. As a PhD student, he investigated the potential applications of near-term noisy quantum computing hardware and developed open-source software for electronic structure applications on quantum computers. After graduating, he joined IBM, where he researches and develops open-source software for quantum computing applications and creates educational content to help users get the most out of IBM's quantum computing services.
