Dec 1, 2025December 2025: Implemented Parity Sampling for PauliLindbladMap with a new parity_sample method, enabling scalable parity-based sampling for quantum operations. The change includes tests, user-facing documentation, and release notes; and removes an outdated rust sample method to streamline parity sampling. No major bug fixes recorded for this period. Impact: improved sampling accuracy and reproducibility for simulations; prepares groundwork for broader parity-based analytics. Technologies demonstrated: Python, Rust interoperability, testing, documentation, release engineering, and code cleanup.

Sep 1, 2025Month: 2025-09 Summary of key outcomes for Qiskit/qiskit: - Delivered phased variants of sparse Pauli representations: PhasedQubitSparsePauli and PhasedQubitSparsePauliList with phase storage, Rust implementations, Python bindings, and conversion utilities to dense forms (to_pauli and to_pauli_list). This enables accurate phase tracking and performance improvements in large circuits. - Implemented robust cross-language conversions: added to_pauli and to_pauli_list converters, facilitating seamless transitions between sparse and dense representations. - Strengthened stability and test coverage: fixed phase handling and equality semantics, expanded tests for compose and commutes, and enhanced from_label/from_sparse_list support; improved default phase handling and pickling compatibility. - Documentation and release readiness: updated release notes and docs to reflect the new phased representations and conversion APIs, improving developer experience and interoperability.
