Russian scientists test a new powerful quantum computer

Researchers at Lomonosov Moscow State University have developed and tested a 72-qubit quantum computing prototype based on single neutral rubidium atoms. The work was reported by TASS.

The prototype uses an atom-based platform and reaches a qubit count of 72. Rosatom Quantum Technologies said the system is the third Russian quantum computer to exceed the 70-qubit level.

The research team introduced a new architecture that separates quantum registers into three functional zones. These zones are designed for computation, long-term quantum state storage, and information readout.

Current experiments used two of the three zones. The computation and storage areas were active, while the readout zone is planned for a later development stage.

According to TASS, tests showed two-qubit logical gate accuracy of 94 percent. The results were obtained during experimental runs of the prototype system.

Yekaterina Solntseva, director of quantum technologies at Rosatom State Corporation, said reaching 72 qubits on an atom-based platform demonstrates steady progress in Russia’s domestic quantum computing program. She noted that improving the reliability of quantum operations remains a central goal.

Solntseva said reducing error rates in quantum logic is required to expand quantum systems to more advanced problem-solving tasks. She added that such progress supports broader national technology objectives.

Stanislav Straupe, head of the quantum computing sector at the Quantum Technology Center at Moscow State University, said the three-zone design allows different quantum tasks to be handled independently. He said development of the third zone will continue in the next phase.

Straupe said scaling the platform to several hundred high-fidelity qubits by 2030 could enable logical operations with error correction. He said this level would support algorithms beyond the practical reach of classical computers.

Vladimir Belokurov, dean of the university’s physics department, said the project involves senior scientists as well as young researchers, graduate students, and undergraduates. He said the effort helps train new specialists in quantum technologies.
