TIM has carried out in Milan the first quantum-safe connection between two Data Centers using Quantum Key Distribution (QKD), a technology based on the principles of quantum physics that enables the generation and exchange of cryptographic keys in an extremely secure way, making any interception attempt more difficult.
The most innovative element of the trial is that the distribution of quantum keys took place over an active commercial network with real traffic, without interrupting services. The quantum signal was transmitted over the same optical fibre used for traditional data, along a route of about 40 km connecting two TIM Group Data Centers in the Milan area. The test, carried out in operational conditions and not in a laboratory, demonstrates that quantum technologies can be integrated into existing network infrastructures.
The trial represents an important step in strengthening the security of the network-data center-cloud ecosystem, which is becoming increasingly strategic for businesses and Public Administration. In this scenario, the ability to protect and govern critical infrastructures and data with robust solutions becomes a competitive factor and enables a model of digital sovereignty based on greater control, technological autonomy and infrastructure resilience, to the benefit of Italy.
The project involved the expertise of the TIM Enterprise ecosystem, with the contribution of Telsy and QTI for quantum security and Noovle for the Data Center infrastructure, and was carried out in collaboration with Cisco. The initiative is part of the broader European commitment to quantum communications, a field in which TIM coordinated the EQUO project funded by the European Commission.
With this trial, TIM takes a further step forward in the development of innovative solutions for communication security and data protection, bringing advanced technologies from the laboratory to the real network and contributing to making digital infrastructures more resilient.
