IBM has announced Qiskit Fermions, an open-source research package that enables the representation of fermionic operators and circuits and postpones their conversion to qubits until the compilation stages. IBM presents an example simulating the Fermi-Hubbard model with constant two-qubit gate depth when using an encoding based on flow groups.
IBM Quantum reviewed a range of research, software, and educational updates in the second quarter of 2026, including the availability of a workflow for simulating a protein comprising 12,635 atoms and an experiment simulating hadron dynamics on real quantum hardware. The platform also unveiled operational metrics and new tools for improving errors and developing circuits and simulations.
