Russia has developed a new technology for the production of superconducting integrated circuits that is based on tantalum. This technology has the potential to improve the country’s position in the rapidly evolving field of quantum computing. The technology was developed by researchers at the Quantum Park of Bauman Moscow State Technical University and the Dukhov Automatics Research Institute (VNIIA). It has already demonstrated resonator quality factors of approximately 10 million in the single-photon regime. According to the developers, the first quantum co-processors that will be used on the new tantalum platform have already been contracted for delivery in autumn 2026. A New Material Platform for Quantum Computing The significance of the development lies not simply in producing another superconducting chip but in establishing a domestic manufacturing process for tantalum-based superconducting integrated circuits. These circuits are regarded as a critical technology for superconducting quantum processors due to their ability to lengthen the lifespan of fragile quantum states and reduce energy losses. The Russian work has been demonstrated on cryogenic microwave resonators, which are critical test structures for superconducting quantum electronics. In accordance with Bauman MSTU, the technology has advanced beyond laboratory experiments and is now in the challenging process of being integrated into serial production. The university has contracted the first deliveries of quantum co-processors that are based on the tantalum platform for autumn 2026. The research was conducted as part of the Bauman DeepTech strategic technology project on exaflops hybrid computing, which is part of Russia’s Priority-2030 program. The underlying scientific results were published in Applied Physics Reviews in 2026. Why Tantalum Matters In superconducting quantum circuits, tantalum is becoming an important alternative to more established materials like aluminum. Nevertheless, the obstacle is that tantalum thin coatings can develop in a variety of crystalline phases. The alpha phase is of
