Worked on quantum computing frameworks by enhancing both Qiskit and Cirq repositories, focusing on correctness and optimization. Addressed a decomposition issue in Qiskit’s MultiplierGate to ensure user-specified result qubits were respected, supplementing the fix with targeted validation tests to prevent regressions. Updated Cirq’s Spin Echoes tutorial to adopt the optimize_for_target_gateset optimizer, aligning documentation and examples with current best practices for circuit optimization. Emphasized reliability by improving test coverage and refining tutorial flows, making the onboarding process clearer for users configuring target gatesets. Utilized Python, quantum computing concepts, and unit testing to deliver robust, user-focused improvements within one month.
