Leonardo P. Top-Executive

I am an R&D Scientist at Quantinuum working at the intersection of AI, machine learning, and quantum algorithms. My work combines deep learning, quantum algorithm design, and practical engineering: building models, training pipelines, and systems that move from research to real deployment.

I specialize in:
• AI/ML Systems — LLMs, AI agents, model training, optimization, experimental pipelines.
• Quantum Algorithms & Quantum AI — error mitigation, Hamiltonian models, quantum machine learning models, quantum generative models, Deep Learning.
• End-to-end Engineering — PyTorch/PyTorch Lightning, Optuna, W&B, robust data workflows and reproducible codebases.

My goal is to build advanced AI systems and contribute to research or products that have real impact. I’m driven by building, experimenting, understanding systems at scale, and pushing technical boundaries in both AI and quantum computing.
