QSpace Technologies LLC, a developer of satellite and atmospheric systems in the field of quantum cryptography, announced the closing of a seed round worth 71.7 million rubles. The investor was Gazprombank, one of the largest commercial investors in quantum technologies in Russia. The investment will be spent on the first phase of building a small CubeSat with a quantum key distribution system transmitter on board. In the future, researchers plan to launch the small vehicle into space, using the transmitter as a payload. The satellite is scheduled for launch in 2023.
Quantum Key Distribution (QKD) is a key technology in the field of quantum communications, allowing for the highest possible level of information security guaranteed by the laws of physics. QRD is already used in modern telecommunications for confidential data transfer, but today the key transfer is performed via fiber-optic cable, which limits it to a distance of 200 km, taking into account the requirement for the speed of generation. By the end of 2024, QSpace Technologies LLC intends to demonstrate a solution to the limited range problem, using a satellite as a "trusted node". QSpace Technologies LLC is a spin-off of the Russian Quantum Center, spun off from quantum cryptography hardware developer QRate in 2021, and a resident of Skolkovo (VEB.RF Group). It is the only company in Russia developing a satellite system based on small spacecrafts.
