PROFILE
William Courtney
Contributed to quantumlib/Cirq by delivering two backend-focused features over two months, emphasizing stability and usability improvements. Developed concurrency throttling for ProcessorSampler workloads, refactoring run_batch_async to accept a maximum concurrency parameter and integrating duet.Limiter for rate control, which reduced backend overload risk and improved throughput during peak demand. Later, enabled the Streaming Engine interface by default through EngineContext configuration, streamlining user workflows and aligning with Cirq’s broader streaming initiative. Work demonstrated proficiency in Python, asynchronous programming, concurrency control, and backend development, with a focus on code refactoring, configuration management, and commit-driven collaboration across the Cirq repository.

Jan 1, 2025January 2025 (quantumlib/Cirq): Key feature delivered was enabling the Streaming Engine by default. Specifically, EngineContext.enable_streaming was set to True, re-enabling the streaming interface and removing the blocking TODO comment. This shipped with commit ecf9ed750ca0d8fcc909b1ff382378ce98133b7b (Re-enable streaming Engine interface) as part of PR #6930. Major bugs fixed: none reported in this scope. Overall impact: reduces configuration friction for users, accelerates adoption of streaming workflows, and aligns Cirq with the broader streaming initiative. Technologies/skills demonstrated: Python EngineContext configuration, commit-driven development, code cleanup (removing TODO), and PR-based change management across the Cirq repository.

Nov 1, 2024November 2024 focused on stabilizing ProcessorSampler workloads in quantumlib/Cirq by implementing concurrency throttling to protect backend services and quotas. Key changes include refactoring run_batch_async to accept max_concurrent_jobs and integrating a duet.Limiter to cap execution rate. These changes reduce risk of backend overload and quota violations during peak demand, improving reliability and throughput for ProcessorSampler workloads. No major bugs fixed this month; primary impact was stability and predictable performance. Technologies demonstrated: Python, asynchronous programming, concurrency primitives, and rate-limiting with duet.Limiter. Related commit: 4bc068c4b3e2a5ad43b67cf2887db3124d936a34 (Add throttle for jobs run with ProcessorSampler (#6786)).
