About the Speaker

Gaetano De Martino holds a degree in Electronic Engineering from the University of Naples Federico II and has over a decade of experience in electronics, experimental physics and telecommunications. He is Head of Engineering at KETS Quantum Security, where he oversees the hardware development of chip based Quantum Key Distribution (QKD) and Quantum Random Number Generator (QRNG) systems. Gaetano developed a single photon detector for QKD applications. Prior to joining KETS, he worked on RF and microwave technologies, delivering high performance solutions for physics, satellite and telecommunications projects.

Chip-based quantum key distribution

Overview

At KETS we develop quantum key distribution (QKD) systems that enable secure communication, resistant to quantum computer attacks. Adoption of QKD has been limited by cost and bulky fibre-based solutions. To overcome these barriers, we created chip-based QKD using photonic integrated circuits manufactured in commercial foundries. We integrate quantum signal generation, detection, and quantum random number generation onto compact chips using platforms like silicon-on-insulator and indium phosphide. Our latest breakthrough combines receiver chips with single-photon detectors, overcoming the last remaining  miniaturization challenges. This allows us to deliver scalable, cost-effective QKD systems and advance large-scale quantum-secure networks and future quantum internet applications.

Key Points

• KETS members pioneered chip-based quantum key distribution systems
• KETS approach will enable small form factor and low cost quantum communications at scale
• As an example, we recently solved the remaining hurdle of integrating single photon detectors with chips
