Researchers at Lomonosov Moscow State University (MSU) and the Russian Quantum Center have developed Russia’s first prototype of a 50-qubit quantum computer based on neutral rubidium atoms. This milestone aligns with Russia’s 2020 Quantum Computing Roadmap, which targets the creation of a quantum system with a minimum of 50 qubits by the end of 2024.
The prototype utilizes single rubidium atoms trapped in optical tweezers formed by focused laser beams. An experimental test of the system was conducted on December 19, 2024. According to the MSU Physics Department’s Quantum Technologies Center, the prototype features a quantum register of 50 atoms arranged in an ordered array. Operations on single qubits are now feasible, marking a critical step forward in quantum technology development.
Stanislav Straupe, head of the quantum computing sector at MSU, highlighted the scaling potential of neutral atom systems, emphasizing their suitability for expanding from tens to hundreds or even thousands of qubits. The system’s core components include a laser setup for cooling and atomic state control, and an ultra-high vacuum optical system.
The project, coordinated under Rosatom State Corporation, represents a significant advancement in Russia’s quantum technology initiatives. For more details, refer to an article posted by the Russian Tass news agency here.
