Russian scientists present 70-qubit quantum computer prototype

Russian scientists have presented a 70-qubit quantum computer prototype developed as part of Rosatom’s Quantum Project, a national programme aimed at advancing quantum technologies. This is reported by "Strana Rosatom". 

Researchers from the Russian Academy of Sciences report that the experimental system has achieved high operational accuracy, with single-qubit operations reaching 99.98 per cent and two-qubit operations 96.1 per cent. Experts say these results are essential for scaling up quantum computing systems.

Earlier, another research team working within related quantum research programmes demonstrated the feasibility of building a 70-qubit quantum register using calcium ions, performing both single- and two-qubit operations. The findings highlight progress across multiple technological approaches.

Specialists note that reaching the 70-qubit level marks an important step toward the practical application of quantum computing. 

"With the achievement of 70-qubits, we are entering a new level of quantum computing development, expanding the scope for practical application of the technology. A large-scale programme of pilot projects for the introduction of quantum computing has been launched in the nuclear industry," stressed Ekaterina Solntseva, Director of Quantum Technologies at Rosatom.

According to the Lebedev Physical Institute of the Russian Academy of Sciences (LPI RAS), Russia plans to develop a medium-scale quantum computer by 2030, incorporating advanced error-correction mechanisms and complex quantum algorithms. These efforts are being carried out as part of the country’s broader quantum technology roadmap.
