PROFILE

Nate Stemen

Worked on quantum computing tools across PennyLaneAI/pennylane, PennyLaneAI/qml, and quantumlib/Cirq, focusing on QASM output optimization, documentation hygiene, and user-facing tutorials. Delivered a Zero-Noise Extrapolation demo in PennyLaneAI/qml using Catalyst and Python, expanding hardware compatibility with OpenCL and improving documentation for user adoption. Addressed QASM output issues in PennyLaneAI/pennylane by refining classical register allocation and fixing parsing compatibility with Cirq, using Python and software testing to ensure robust cross-tool workflows. Updated branding and removed outdated references in quantumlib/Cirq documentation, maintaining ecosystem consistency. Collaborated closely with contributors, emphasizing maintainable code and clear, actionable documentation throughout.

1 Commits

Feb 1, 2026

February 2026 monthly summary focusing on QASM export optimization in PennyLane to remove unused classical registers, delivering a bug fix that reduces the number of classical registers instantiated in QASM when measurements are not required. Implemented wire-measurement analysis to allocate classical registers only for wires with measurements, addressing edge cases and aligning with user expectations. Related to PR #9033 and PennyLane issue #9024. Collaborative effort with Gabriela Sánchez Díaz and Marcus Edwards. Commit involved: 88f4b954ffe6ff96506cf468ab51a701e273ef40.

November 2024 monthly summary: Delivered a Zero-Noise Extrapolation (ZNE) Demo Tutorial with Catalyst in PennyLaneAI/qml, including a performance comparison with the pure PennyLane path, an OpenCL build setup, and updates to package dependencies. The work provides a practical ZNE workflow for users, improves testability, and broadens hardware support. Committed changes consolidated in 22a96cd8e056366ff789f4db96f6dc4ce1c8932f (ZNE demo using catalyst (#1207)).
