Russian Quantum Network Node for the Internet of the Future Created

NUST MISIS conducted a demonstration of the operation of a domestic quantum network node developed by scientists from the NTI Center for Quantum Communications. The shown node will become the basis for creating demonstration quantum computers and prototyping quantum internet devices.

The quantum network node developed by the scientists of the NTI Center for Quantum Communications of NUST MISiS is used for demonstration and research work in the field of quantum communications and photonics on the basis of universities, R&D centers and research and production associations.

The complex consists of two blocks connected by a fiber-optic communication line and implements the so-called two-pass system, in which the receiver generates a sequence of laser pulses and sends them to the transmitter. It turns out a distributed random number generator.

A distinctive feature of this hardware-software complex is its configuration flexibility, which distinguishes it from analogues. Modularity allows you to modify optical circuits, vary electronic components, explore promising protocols, and develop interfaces for integrating quantum communications into other information systems.

According to the developers, in the future this node of the quantum network will become the basis for creating a generation of demonstration quantum computers for solving educational and scientific problems based on optics. It will also be used to prototype quantum internet devices: the next generation of quantum technologies that will allow remote quantum computers to be used and connected to a common network. This is one of the key areas of work for NUST MISIS scientists as part of the Priority 2030 program.

In fact, other computing devices — the prototype of the quantum internet — and sensor systems for the “quantum internet of things” will be able to connect to the presented node in the future. In particular, the laboratory “Superconducting Metamaterials” of NUST “MISiS” works in this direction, in which prototypes of quantum processors and microwave interfaces for their connection into a quantum network are created.
