The Italy telecom sector has wrapped up a major three-year research sprint, delivering quantum encryption networks, earthquake-detecting fiber cables, and AI-powered smart grids—all financed through the Italian National Recovery and Resilience Plan (PNRR) with €116M in public funds. The findings, presented this week by Open Fiber, the country's wholesale fiber operator, mark a shift from lab experiments to potential commercial deployment across critical infrastructure.
Why This Matters
• Quantum-safe communications are moving from theory to practice, with encryption keys distributed through existing fiber networks—no new cables required.
• Fiber-optic seismic sensors tested in the Campi Flegrei volcanic zone could augment Italy's early warning systems for earthquakes and volcanic activity.
• Micro-data centers built into network nodes promise faster response times and lower energy consumption for cloud services.
• Smart grid pilots in Bergamo have already demonstrated how fiber, 5G, and AI can optimize renewable energy sharing in residential and business communities.
What Restart Delivered
The RESTART program (RESearch and innovation on future Telecommunications systems And networks, to make Italy more smART), launched in January 2023, concluded its reporting phase on June 30. Across 32 projects and 135 partners—ranging from telecoms to universities and research institutes—the initiative targeted next-generation network security, efficiency, and intelligence. Open Fiber contributed to six projects with a budget of €1.75M, producing 22 demonstrations and proof-of-concept prototypes alongside 25 peer-reviewed papers.
"Restart allowed us to embed research directly into the network and field-test how an infrastructure designed to carry data can become a platform for new services," said Giuseppe Gola, CEO of Open Fiber. The company's priority now is scaling the most viable solutions toward industrial applications that enhance infrastructure efficiency and unlock new market opportunities.
Quantum Encryption Without New Fiber
One standout result is a quantum key distribution (QKD) network that transmits cryptographic keys immune to both current and future quantum-computing attacks. Open Fiber demonstrated that 100 Gbps data streams and quantum channels can coexist on the same commercial fiber, eliminating the need for parallel infrastructure. This approach aligns with Italy's participation in EuroQCI, the EU's quantum communication backbone, which will link Rome, Naples, Turin, Florence, and Matera.
QTI (Quantum Telecommunications Italy), a spin-off of the National Research Council's Institute of Optics (CNR-INO), is already manufacturing commercial QKD devices under the Quell-X brand. In 2026, QTI activated a long-distance quantum-safe link between data centers in Rome and Naples, blending QKD with post-quantum cryptography (PQC) for layered defense. The global QKD market is forecast to hit $1.61B in 2026, growing at a compound annual rate above 31% through 2035, driven by demand from banks, governments, healthcare networks, and utilities facing quantum-computing threats.
Fiber as a Seismic Sensor
Another application transforms ordinary fiber cables into a distributed acoustic sensor (DAS) capable of detecting ground vibrations and seismic waves. Under the MEGLIO project (Measuring Earthquakes signals Gathered with Laser Interferometry on Optic Fibers), Open Fiber, INGV (Italy's National Institute of Geophysics and Volcanology), and INRIM recorded dozens of seismic events over two years using a 20-kilometer fiber loop connecting Bagnoli to Bacoli in the Campi Flegrei caldera, one of Europe's most closely watched volcanic zones.
On February 26, INGV and FiberCop signed a memorandum of understanding to integrate FiberCop's nationwide fiber grid into Italy's seismic and volcanic monitoring infrastructure. Earlier trials on Vulcano Island detected more than 1,400 seismic events in a single month, offering granular insights into hydrothermal systems. While traditional seismometers provide point measurements, DAS turns every meter of fiber into a sensor, vastly expanding coverage without additional hardware installation.
Micro-Data Centers and AI Traffic Forecasting
Two micro-data center prototypes, designed to fit into existing fiber-network nodes, were built and tested during Restart. By processing data closer to its source—edge computing—these units reduce latency and energy consumption, a critical advantage for applications such as autonomous vehicles, industrial automation, and real-time video analytics.
Separately, AI models trained to predict traffic peaks were deployed to optimize bandwidth allocation dynamically. A remotely reconfigurable optical switch adds another layer of flexibility, allowing network operators to reroute data flows without dispatching technicians.
Smart Grid Pilot in Bergamo
In Bergamo province, the TeleSmEg project combined fiber, 5G, edge computing, cloud, and AI to coordinate energy flows within Renewable Energy Communities (CER)—groups of households, offices, and electric-vehicle charging stations that generate and share solar power. Over the trial period, the community produced 3,199 kWh, of which 1,329 kWh were shared internally, with 71% of grid-injected energy consumed within the community. The results underscore how connectivity and intelligent data processing can maximize self-consumption and stabilize future smart grids.
Bergamo leads Lombardy in active energy communities, with 10 CERs and 15 collective self-consumption groups totaling over 1 MW of installed capacity across 323 municipalities. Local AI firm Evogy, which uses predictive analytics to manage building climate systems, reported savings of 1.6 GWh of electricity, 400,000 cubic meters of gas, and 1,000 tons of CO₂ across its client portfolio in 2024 alone.
Impact on Residents and Investors
For residents, these technologies translate into more reliable utilities and lower energy bills. Quantum-safe encryption protects personal banking, healthcare records, and government services from future cyber threats. Fiber-optic seismic sensing could shorten warning times for earthquakes, particularly valuable in densely populated volcanic zones like Campi Flegrei and Mount Vesuvius. Smart grids enable apartment buildings and small businesses to join energy communities, selling surplus solar power back to neighbors and slashing electricity costs.
From an investment perspective, Italy's telecom research ecosystem is producing spin-offs and partnerships with immediate commercial trajectories. QTI, ThinkQuantum, and Quantum2Pi are all Italy-based quantum-communication startups now courting international clients. TIM Group, through its security subsidiary Telsy and undersea-cable operator Sparkle, completed Italy's first quantum-safe data-center link on a production network, signaling operator readiness for enterprise rollouts.
Parallel PNRR Milestones
Restart is one piece of a broader PNRR telecom push. The Italia 1 Giga Plan, also funded by PNRR, aims to deliver ultra-fast broadband to underserved "grey zones" by June 30, 2026. The Italia 5G Densification Plan met its May 31 target of covering 500 square kilometers with 5G mobile connectivity. A separate National Connectivity Fund closed a May 11 call for projects capable of delivering at least 1 Gbit/s speeds.
What Comes Next
Open Fiber and its research partners are now evaluating which prototypes merit full-scale deployment. Quantum encryption is nearest to market, with equipment vendors ready and operators testing integration. Fiber-optic sensing requires coordination with civil-protection agencies but faces no major technical hurdles. Micro-data centers and AI traffic management hinge on business-model clarity—edge computing competes with centralized cloud economics, and operators must decide whether to build, lease, or partner.
The broader question is whether Italy can convert public research euros into private-sector revenues. With 135 partners trained, 25 papers published, and 22 working prototypes delivered, Restart has produced intellectual property and know-how. Turning that into jobs, exports, and infrastructure resilience is the next test for Italy's telecom industrial policy.
