Over a three-month period, contributed to the CQCL/tket repository by delivering three targeted features focused on quantum circuit optimization and synthesis. Enhanced circuit analysis by exposing implicit wire swaps and introducing configurable swap handling, using Python and C++ for interface design and test-driven development. Developed a flexible CnX gate decomposition method supporting ancilla qubits in various states, expanding synthesis capabilities for multi-controlled operations. Optimized the Greedy Pauli Optimisation pass, achieving a substantial reduction in wall-clock time for large circuits through refined lookup tables and cost calculations. Demonstrated strengths in algorithm implementation, performance engineering, and cross-language integration within quantum computing workflows.

Apr 1, 2025April 2025 performance-focused update for CQCL/tket. Delivered a major optimization to the Greedy Pauli Optimisation pass, achieving approximately 40% reduction in wall-clock time for GreedyPauliSimp on large circuits. The optimization refines lookup tables and cost calculations within GreedyPauliOptimisation, powered by the feature work under Transforms::greedy_pauli_optimisation. This work is tracked under commit a61bbac1c07487521acd8da463023f3c85c799e8 and aligns with performance engineering goals aimed at scalability and throughput.
