Russia has completed the installation and commissioning of a pilot project to protect financial infrastructure using quantum communications. As part of the initiative, secure communication channels operating on the basis of the Russian Railways (RZD) backbone quantum network have been established between the data centers of the Federal Treasury and PSB Bank. According to the participants, this is the first time in the country that quantum key distribution (QKD) technology has been used to connect the operating infrastructure of a government agency and a commercial bank. The Financial University under the Government of the Russian Federation is also participating in the project.
Project Architecture and Participants
RZD plays a key infrastructural role in the project, as its backbone quantum network serves as the transport circuit for transmitting encryption keys between two remote facilities. The Federal Treasury and PSB Bank acted as customers for the secure channels, while the Financial University under the Government of the Russian Federation was brought in as a scientific and analytical partner. Equipment has already been installed at both ends of the line, installation and commissioning work has been completed, and the participants have confirmed the standard operation of the channels and moved on to the testing phase.
Technical Parameters of the Quantum Channel
The network provides traffic encryption at speeds of up to 10 Gbps over a distance of more than 1,200 km. Encryption keys are generated and transmitted to connected facilities automatically, without operator intervention. Network management and round-the-clock monitoring of its status are carried out in a specialized RZD center, which makes it possible to respond promptly to anomalies and maintain the required level of channel availability. Such an architecture eliminates manual key entry and minimizes the human factor in the cryptographic cycle.
Protection Against Future «Quantum Threat»
The main task of quantum key distribution is to reduce the risk of interception and subsequent decryption of data using future quantum computers. Classical encryption algorithms used today to protect financial flows are potentially vulnerable to a sufficiently powerful quantum processor. QKD, on the other hand, is based on the laws of quantum physics: any observation of the state of photons carries a detectable disturbance, which makes covert interception of the key fundamentally impossible. Thus, even if data is intercepted today, it will be impossible to decrypt it without a key in the future.
Expansion Prospects and Sovereignty
Project participants announced their intention to expand the use of quantum solutions to other strategically important objects of the financial system. The development of its own quantum infrastructure is viewed as a way to reduce dependence on foreign cryptographic technologies and ensure technological sovereignty in the field of data protection. The initiative fits into a broader context: back in June 2026, the Kremlin's IT department emphasized that Russia needs to build its own «quantum shield» — a comprehensive system of quantum technologies to protect critical infrastructure.
From Laboratory to Industrial Operation
The completion of the pilot stage between the Treasury and PSB marks the transition of quantum communications from the laboratory and demonstration plane to real industrial operation on existing infrastructure. The RZD backbone network, stretching over a thousand kilometers, has proven that quantum channels are capable of operating under real operational loads, rather than just in controlled laboratory conditions. Successful testing paves the way for scaling the technology to interregional and interdepartmental communications, which in the future could form a unified quantum-secure network for the country's financial infrastructure.
