A research project on photonic integrated quantum cryptography systems funded by FISA (Fondo Italiano per le Scienze Applicate)
Quantum technologies are set to revolutionize secure communications. As quantum computers threaten current encryption approaches, Quantum Key Distribution (QKD) provides a fundamentally secure method for key exchange based on quantum mechanics. The PIQCS project addresses the limitations of current QKD systems—typically bulky, expensive, and power-intensive—by leveraging Photonic Integrated Circuits (PICs).
By integrating QKD and Quantum Random Number Generation (QRNG) on compact photonic platforms, PIQCS aims to deliver scalable, efficient, and practical devices for quantum-secure networks, aligned with major European strategic initiatives.

The PIQCS project addresses the key technological barriers that currently limit the large-scale deployment of practical quantum cryptography systems. The aim is to develop a complete Photonic Integrated Quantum Cryptography System by combining advanced academic research and industrial know-how.
The project focuses on industrializing the critical components required for integrated QKD systems using three main platforms: Silicon-on-Insulator (SOI), Indium Phosphide (InP), and Silicon Nitride (SiN).
Design and characterization of single components on SOI, InP, and SiN platforms, addressing the project's core fundamental research phase.
Technology refinement to improve performance, robustness, and scalability for industrial application.
Prototype realization and integration into QKD systems, followed by laboratory and field testing.
Development of high-speed digital and RF electronics for managing and stabilizing PICs, culminating in a full QKD protocol demonstration.
Although QKD and QRNG are scientifically mature technologies, their widespread deployment remains constrained by cost, footprint, and power consumption. Current systems often rely on bulky fiber-optic components requiring expensive manual assembly.
Photonic integration transformed classical optical communications by enabling large-scale integration of optical components on chip. PIQCS seeks to apply a similar paradigm to quantum photonic systems.
Quantum applications require much tighter control and lower losses than classical systems. PIQCS aims to bridge the gap between state-of-the-art academic demonstrations and commercially robust products.
