Senior Staff, Quantum Solutions at IonQ
Zurich, Zurich, Switzerland
Summary
🤩
Rockstar🎓
Top SchoolPanagiotis Barkoutsos is a Senior Staff in Quantum Solutions based in Zurich with a six-year professional track record bridging academic quantum theory and commercial quantum software. He has held research and leadership roles at IBM, Pasqal and now IonQ, driving quantum algorithms, applications and R&D from PhD-era simulation work through product-focused teams. His contributions to prominent open-source Qiskit projects (notably qiskit-nature and qiskit-aqua) show hands-on backend expertise in fermionic operators and particle-hole transformations used in quantum chemistry. Comfortable moving between deep theoretical problems and production-quality code, he blends rigorous physics training (PhD, ETH Zurich) with practical software engineering and documentation improvements. A less obvious strength is his consistent focus on robustness—bug fixes, test additions and refactors—that make cutting-edge quantum algorithms more reliable for users and integrators.
