Summary
🤩
Rockstar🎓
Top SchoolAntal Száva is a Quantum Research Software Developer with 9 years of engineering experience and 5+ years focused on quantum computing, blending hands-on Python/C++ development with research-grade protocol design. He led the PennyLane core team at Xanadu, managing major releases, JAX integrations, and contributor growth while also contributing performance and simulation features to the widely used Strawberry Fields photonic library. After Xanadu he developed fault-tolerant and QEC tooling at QC Design—adding IBM backend connectivity and dynamic-circuit simulators—and now works on secure quantum cloud protocols in a European QuantERA project at ELTE. He also contributes to Piquasso at the Wigner Research Centre, signaling continued commitment to open-source photonic tooling. Trained at TU Delft (thesis on quantum network routing at QuTech), Antal combines product-facing release discipline with deep research experience across networking, error correction and secure quantum services. Colleagues rely on him for pragmatic architecture decisions that bridge prototype research and production-ready quantum software.
