The laboratory, under the supervision of Dr. Massimiliano Proietti, conducts research across various areas of quantum technology, ranging from quantum multidomain networks to quantum sensing for position, navigation, and timing (PNT) and quantum imaging. It also plays an active role in many national and international projects as well as in relevant standardization bodies.

This research area, led by Dr. Carlo Liorni, focuses on quantum communication networks spanning multiple physical domains (terrestrial, free space, satellites). Quantum multidomain networks are being deployed worldwide to interconnect quantum devices and processors, enabling enhanced sensing capabilities, scaling up computing power, and establishing secure communication infrastructures thanks to quantum key distribution (QKD) and other cryptographic primitives.

What we do

• At the physical layer, we develop QKD systems (HW and SW) in fiber and free space. This includes critical components and software such as quantum random number generators, pointing and tracking mechanisms, quantum light sources and efficient post-processing.
• At the network layer, we integrate quantum and post-quantum solutions through custom key management systems. We deploy QKD networks over telecom fibers such as the Rome Quantum Metropolitan Area Network.
• Study and implement characterization techniques and countermeasures against quantum hacking on QKD systems.

This research area, led by Dr. Alessia Suprano, focuses on the development of advanced imaging technologies capable of delivering superior performance in degraded visual environments and covert conditions, paving the way for the next generation of detection and surveillance systems. These technologies play a crucial role in improving situational awareness and information gathering across a wide range of sectors, including airborne, land, naval, and space platforms.

What we do

• We study and develop quantum imaging solutions based on quantum entanglement, which exploit the natural covertness of single-photon-level illumination and quantum correlations to improve performance in terms of resolution and coverage.
• We design and implement LiDAR systems that use state-of-the-art single-photon detectors to enable non-line-of-sight imaging, allowing vision around corners, behind obstacles or obscurants.
