One of the most important quantum communication infrastructures in Europe has already deployed the first phase. This year 16 operating devices will be deployed, and another 6 are in progress. In this network, quantum algorithms will be studied, which will improve security in areas such as telecommunications, medical care, power supply or public services.
Madrid’s new quantum communication network is called MadQCI (Madrid Quantum Communication Infrastructure), Is an infrastructure that integrates quantum communications into conventional optical networks.
It is one of the most important test benches in Europe with the above characteristics. Computing Simulation Center (CSC) Polytechnic University of Madrid (UPM) work together Telefónica And research institute IMDEA software (REDIMadrid).
The network is part of the European project OPENQKD And the first phase of its deployment has already begun. There are currently 16 types of quantum communication devices, of which 10 have been deployed, and the other 6 are being tested in the laboratory. Before these, six more will be added before the summer, thus completing the first phase.
In this Madrid network, the security technology is called Quantum safe, Even attacks from quantum computers are safe. Quantum algorithms will be studied, which will improve the security of critical applications in areas such as telecommunications, healthcare, power supply, and utilities.
The infrastructure will also be used for technologies developed in industrialization projects, such as CiViQ, Which belongs to the European plan Quantum flagship. This ten-year project is Europe’s commitment to leading a new generation of quantum technology.
QKD quantum technology
He said: “These technologies have begun to mature enough to make some of them leap into the market. The so-called “quantum key distribution” is one of the most advanced technologies.” Vicente Martin Ayuso, The researcher in charge Information and Quantum Computing Research Group (GIIC) and CSC director.
Expert refers to quantum technology QKD, its English abbreviation is Quantum key distribution, Is a form of encryption that can transmit data at a high level of security based on the basic principles of quantum mechanics, and solves the problem that the security of any type of computer (including quantum computers) is vulnerable to attacks using traditional encryption technology.
The integration of QKD in a commercial optical network environment is very complicated, because it means that the same infrastructure must be between the signal carried by a single photon (quantum channel) and the typical signal in commercial transmission (each pulse uses billions of photons). Transfer and distinguish between. . Any one of these photons entering the quantum channel will make it ineffective. To make quantum channels compatible with classical channels requires the use of technology at all levels, from physical filters to the use of new networks and quantum communication protocols.
This is not the first quantum network established by UPM in Madrid. The first prototypes were manufactured in a test facility in cooperation with Telefónica 10 years ago. In 2018, Feiyue gained groundbreaking experience on a global scale, demonstrating the application of quantum cryptography in commercial optical networks and its integration with network operations.
“The ability to use technologies such as SDN (software-defined networking) designed to improve network flexibility and new QKD technologies allows us to integrate traditional networks and quantum networks on the existing fiber optic infrastructure. Martín said that we have for the first time to increase The ability to deploy quantum communications in a quantitative manner without having to spend a lot of initial investment costs and use the same infrastructure.
UPM’s GIIC team leads the optical network QKD activities in the European OPENQKD project and the CiViQ project, which is the first of Quantum flagship and European Quantum Communications infrastructure projects.
These initiatives are the foundation of Europe’s scientific and technological leadership in the field of quantum technology, and hope to promote strong cooperation between research, industry and the public sector to create an innovative ecosystem, thereby providing a new perspective for ensuring safety. Digital Europe, thus laying the foundation for the next generation of communication technology.
