Pau Escofet

PhD Candidate in Quantum Computing Architectures

Bridging the gap between theory and implementation in quantum systems. I focus on quantum circuit compilation, error correction, and graph-based modeling to enhance the scalability and performance of realistic quantum devices.

Biography

I am a PhD student at the Universitat Politècnica de Catalunya (UPC Barcelona Tech), conducting my research at the Nanonetworking Center in Catalunya (N3Cat). My work explores the scalability of quantum computing architectures, bridging the gap between theoretical algorithms and physical implementation. I hold a Bachelor’s in Computer Science and a Master’s in Advanced Communication Technologies from UPC.

Supervised by Prof. Eduard Alarcón, Dr. Carmen G. Almudéver, and Dr. Sergi Abadal, I focus on quantum circuit compilation, quantum error correction (QEC), and graph-based techniques to guide and improve the design of large-scale quantum computing architectures.

My academic journey has been defined by international collaboration. Currently, I am a visiting graduate student at Princeton University (2025-2026), working with Prof. Margaret Martonosi on the design of scalable, modular, fault-tolerant quantum computing architectures. Previously, I was a visiting student at Equal1 (2024), co-designing QEC-aware architectures and compilers for silicon spin qubits, and completed a research stay at CESGA (2025) studying the calibration drift in superconducting qubits. During my Bachelor's, I completed an exchange semester at ETH Zurich (2021-2022). Prior to that, I conducted research on piezo-electric materials at IES Montpellier (2016) with Dr. Adrian Carretero and Dr. Laura Piques.
