In February 2026, the team delivered a foundational feature in HEPLean/PhysLean that enables d-dimensional quantum mechanics operator modeling, laying groundwork for multi-dimensional quantum simulations. The work focuses on defining position, momentum, and angular momentum operators in arbitrary dimensions along with their commutation relations, enabling more realistic and scalable quantum simulations within the project. There were no major bugs fixed this month. Impact and business value: This establishes a scalable operator framework that broadens PhysLean’s applicability to complex quantum systems, accelerating modeling capabilities for research workflows and time-to-insight in quantum physics simulations. The work also improves traceability and sets a clear pathway for future enhancements in quantum algorithms and higher-dimensional modeling. Technologies/skills demonstrated: multi-dimensional operator algebra, quantum mechanics formalism, modular API design, code/documentation discipline, and Git-based traceability.
