Clarity at the edge of quantum & AI.
I'm George Jiri Spitalsky — a quantum and AI researcher and creative developer. I design algorithms, scale GPU-accelerated quantum simulation, and turn frontier research into clean, working software.

About
From a multilingual GPT in 2020 to multi-GPU quantum simulation today.
George (spital) works where quantum computing meets artificial intelligence. He's a Qiskit Advocate, holds 15+ quantum credentials on Credly, and was personally recommended by an IBM manager. He completed every lab during Qiskit Global Summer School's dev week and will mentor at QGSS 2026 this July.
His open-source work spans quantum software — including five accepted pull requests during UnitaryHack 2026 — alongside machine learning and low-level systems work in RISC-V. On the HPC side, he runs distributed statevector simulation with NVIDIA CUDA-Q across multiple GPUs and nodes.
In 2020 — years before ChatGPT — he built a GPT-2-based conversational model with translation across Czech, English, Arabic, Polish, and German. The instinct is always the same: take what's barely possible and make it real, reproducible, and useful.
Selected work
Research that ships.
A portfolio across quantum HPC, language models, and open-source quantum software — each with a real, verifiable trail.

From frontier idea to reproducible result.
A clear, low-risk path for research engagements, quantum prototypes, and applied-AI builds.
1
Discovery
We scope the problem together — quantum feasibility, AI architecture, constraints, and the metrics that define success.
2
Design
I design the algorithm or model, prototype the core, and deliver a clear technical plan with milestones.
3
Build
Implementation with reproducible, tested code and real quantum-backend or multi-GPU integration.
4
Deliver
Documentation, benchmarks, and a clean handover — with optional ongoing research support.
Social proof
Trusted by people who ship hard things.
Recognition from industry and the open-source quantum community — all independently verifiable.
★★★★★
George pairs genuine quantum depth with the engineering discipline to actually ship. A rare combination on any team.
★★★★★
His CUDA-Q simulation scaled cleanly across nodes — exactly the kind of HPC-quantum engineering the field needs right now.
★★★★★
Five accepted PRs in a single hackathon. He simply understands open-source quantum software and how to contribute well.
Let's build something remarkable.
