In January 2026, Anan expanded operator compatibility in the Qiskit/qiskit repository by adding SparseObservable support to the evolved_operator_ansatz module. Using Python and integrating with Rust for performance, Anan implemented robust import handling and optimized logic for edge cases such as empty or identity-only circuits. The work included direct SparseObservable imports, which simplified maintenance and improved reliability. Comprehensive testing was introduced to ensure coverage of new and existing functionality, with updates to release notes reflecting these enhancements. This contribution broadened the range of quantum operators supported, resulting in safer defaults and more reliable operator handling within the quantum computing framework.
