Scientists at Lomonosov Moscow State University and the Russian Quantum Center have developed Russia’s prototype of a 50-qubit single cold atom quantum computer. The project is part of the Quantum Computing Roadmap coordinated by the Rosatom State Corporation, which aims to create a quantum computer with a capacity of at least 50 qubits by the end of 2024.
Stanislav Straupe, head of the quantum computing sector at the Quantum Technologies Center of the MSU Physics Department, led the development of the supercomputer prototype, which utilizes single neutral rubidium atoms captured by optical tweezers.
The technology has promising scaling prospects, potentially expanding from systems of tens of qubits to hundreds and even thousands of qubits. The achievement marks a milestone in Russia’s pursuit of advancing quantum computing capabilities, with several research groups working on different technological platforms, including neutral atoms, ions, superconductors, and photons.
Introduction to Quantum Computing in Russia
The development of quantum computing has been a significant area of research in recent years, with various countries investing heavily in this technology. In Russia, the government has approved a roadmap for the development of high-tech fields, including quantum computing, with the goal of creating a quantum computer with a capacity of at least 50 qubits by the end of 2024. To achieve this goal, several research groups are working on developing prototypes using different technological platforms, such as neutral atoms, ions, superconductors, and photons.
One of the research groups, consisting of scientists from the Lomonosov Moscow State University and the Russian Quantum Center, has made a notable breakthrough in this field by presenting Russia’s first prototype of a 50-qubit single cold atom quantum computer. This achievement is a result of the Quantum Computing Roadmap coordinated by the Rosatom State Corporation. The created calculator is based on single neutral rubidium atoms, which are captured by optical tweezers (focused laser beams). This technology has shown promising results in terms of scaling prospects, with the potential to create quantum registers of hundreds and even thousands of qubits.
The experiment that allowed testing the supercomputer prototype took place on December 19, and the Moscow State University has reported the results. The supercomputer prototype is an optical table, most of which is occupied by a laser system used for cooling and controlling atomic states, as well as a system with ultra-high vacuum and optical access. According to Stanislav Straupe, the head of the quantum computing sector at the Quantum Technologies Center of the MSU Physics Department, the MSU Center for Quantum Technologies is capable of creating quantum registers of 50 atoms arranged in an ordered array and performing operations on single qubits.
The use of neutral atoms in optical tweezers has been identified as a good system in terms of scaling prospects. The scientists involved in this project believe that they more or less understand how to get from systems of tens of qubits to hundreds and even thousands of qubits. This is a significant step forward in the development of quantum computing, as it can potentially solve complex problems that are currently unsolvable with traditional computers.
Quantum Computing Technology
The technology used in the 50-qubit single cold atom quantum computer is based on single neutral rubidium atoms, which are captured by optical tweezers (focused laser beams). This approach has several advantages, including the ability to create quantum registers of hundreds and even thousands of qubits. The use of neutral atoms in optical tweezers also allows for precise control over the atomic states, which is essential for quantum computing.
The supercomputer prototype is an optical table that consists of a laser system used for cooling and controlling atomic states, as well as a system with ultra-high vacuum and optical access. The laser system is used to cool the atoms to extremely low temperatures, which is necessary for quantum computing. The ultra-high vacuum system is used to prevent collisions between the atoms and other particles, which could cause errors in the quantum computations.
The scientists involved in this project have reported that they are capable of creating quantum registers of 50 atoms arranged in an ordered array and performing operations on single qubits. This is a significant achievement, as it demonstrates the potential for scaling up the number of qubits in a quantum computer. The use of neutral atoms in optical tweezers has been identified as a promising approach for quantum computing, with potential applications in fields such as chemistry, materials science, and optimization problems.
The development of this technology is ongoing, with researchers working to improve the control over the atomic states and increase the number of qubits in the quantum computer. The ultimate goal is to create a quantum computer that can solve complex problems that are currently unsolvable with traditional computers. This will require significant advances in the technology, including the development of more sophisticated algorithms and the improvement of the quantum error correction techniques.
Quantum Computing Applications
The potential applications of quantum computing are vast and varied, ranging from chemistry and materials science to optimization problems and machine learning. One of the most promising areas is chemistry, where quantum computers can simulate the behavior of molecules and predict their properties. This could lead to breakthroughs in drug discovery and materials science.
Another area where quantum computing has significant potential is optimization problems. Quantum computers can be used to solve complex optimization problems that are currently unsolvable with traditional computers. This could have major implications for logistics, finance, and energy management. For example, a quantum computer could be used to optimize the routing of trucks in a logistics network, leading to significant reductions in fuel consumption and emissions.
Quantum computing in machine learning is also an area of active research. Quantum computers can be used to speed up certain types of machine learning algorithms, such as k-means clustering and support vector machines. This could lead to breakthroughs such as image recognition and natural language processing.
However, the development of practical applications for quantum computing is still in its early stages. Significant technical challenges need to be overcome before quantum computers can be used to solve real-world problems. These challenges include the development of more sophisticated algorithms, the improvement of quantum error correction techniques, and the scaling up of the number of qubits in a quantum computer.
