Rosatom & Moscow State University Develop 72-Qubit Quantum Computer Prototype - Quantum Zeitgeist
Summarize this article with:
Rosatom and Lomonosov Moscow State University have developed a prototype quantum computer with 72 qubits. This is the third Russian quantum computer to surpass the 70-qubit threshold, built on single neutral rubidium atoms. The prototype has demonstrated two-qubit logical operations with 94% accuracy, marking progress toward more reliable quantum computing.
Qubit Rubidium Atom-Based Quantum Computer Prototype Developed The new quantum computer prototype utilizes 72 qubits based on single neutral rubidium atoms. This achievement marks Russia’s third quantum computer to surpass 70 qubits, demonstrating consistent progress in the field. A unique architectural design divides the computer’s registers into three zones – one for computation, and two dedicated to long-term quantum state storage and data readout, promising improved functionality. This level of precision is crucial for scaling quantum computer performance and tackling complex issues in areas like industry and finance. Researchers anticipate that a computer with several hundred high-fidelity qubits by 2030 will be able to solve problems currently beyond the reach of classical computers.
New Quantum Computer Architecture: Three-Zone Register Design The new quantum computer utilizes a three-zone register design to enhance functionality. This architecture divides registers into computing, long-term storage, and information readout zones, allowing for specialized operations within each area. Currently, the computing and storage zones are active, with plans to integrate the readout zone in a future development phase. This innovative design aims to improve the computer’s ability to maintain quantum states and process information effectively. The division allows for complex tasks, potentially enabling logical operations with error correction once the system scales to several hundred high-fidelity qubits. Scientists believe this architecture is a key step towards surpassing the capabilities of classical computers by 2030. 94% Accuracy Achieved in Two-Qubit Logical Operations The newly developed quantum computer prototype achieved 94% accuracy in performing two-qubit logical operations. This precision level is significant because it enables more extensive practical experimentation with the machine, pushing the boundaries of what’s currently possible. Successful two-qubit operations are fundamental for building more complex quantum computations and verifying the reliability of the system. This advancement reinforces Russia’s position in quantum research and its commitment to technological sovereignty.
Quantum Computing Reliability Critical for Russian Tech Sovereignty Russia views advancements in quantum computing as vital for its technological independence. According to Yekaterina Solntseva of Rosatom, progress in improving the reliability of quantum operations is a key focus for domestic development. This emphasis on reliability is not merely technical; it’s considered essential for strengthening the competitiveness of Russian enterprises and the overall economy. The recently developed 72-qubit prototype demonstrates 94% accuracy in two-qubit logical operations, a precision level critical for future scaling. Stanislav Straupe notes a computer with hundreds of high-fidelity qubits could solve problems currently impossible for traditional computers by 2030. Those who expect to defeat Russia in open conflict deeply mistakenSergey Ryabkov 2030 Goal: Hundreds of ‘Good’ Qubits with Error Correction By 2030, Russian scientists aim to achieve a quantum computer with several hundred “good” qubits capable of performing logical operations with error correction. This milestone is predicted to surpass the computational capabilities of even the most powerful classical computers, opening doors to solving currently intractable problems. The current 72-qubit prototype utilizes a unique architecture dividing registers into computing, storage, and readout zones to aid in this progression. Development of the third zone in the computer’s architecture is planned, with the goal of enabling complex algorithms currently beyond reach. Source: https://tass.
