David Elkouss holds master's degrees in electrical engineering from Universidad Politécnica de Madrid (UPM) and Telecom Paris. During his master's studies, he became passionate about (classical) error correction and the fundamental limits of communications. He moved to the computer science faculty at UPM to earn his Ph.D. optimizing error-correcting codes for quantum key distribution. After the Ph.D., he held two postdoctoral positions. The first one was at the Faculty of Mathematics in Universidad Complutense de Madrid, where he studied the mathematical properties of quantum communications channels. The second one was at QuTech in TU Delft, where he worked in the first loophole-free Bell experiment. Later, he started his own theory group at QuTech within the Quantum Internet and Networked Quantum Computation division. In 2022, he moved to OIST to start NetQ, the networked quantum devices unit, and develop theoretical tools for enabling near-term quantum devices to perform communications, computational and cryptographic tasks.
