Russia has unveiled its first domestic ion-based quantum computer, developed by scientists at the Russian Quantum Center (RQC).<\/strong><\/p>\n The RQC announced on Monday, via TASS, that the device utilizes a novel quantum unit with seven energy levels. This architecture makes the system as powerful as a 72-qubit quantum processor, allowing it to perform critical calculations with extremely high accuracy.<\/p>\n Maxim Ostras, head of the RQC, explained that researchers began testing this multi-level approach in 2021 with a much smaller system.<\/p>\n \u201cOver just four years, we have significantly increased the computing power and created a prototype equivalent to 72 qubits,\u201d he stated.<\/p>\n Most quantum computers today use qubits, which are the quantum equivalents of classical bits. A standard qubit possesses only two possible energy levels, similar to an artificial atom.<\/p>\n However, scientists are now developing more complex units\u2014such as three-level or four-level systems\u2014because they can store and process more information using fewer particles. While more powerful, these systems are typically much harder to control.<\/p>\n Russia\u2019s new machine is composed of 26 calcium ions, with each ion acting as a seven-level quantum unit (capable of taking values from zero to six).<\/p>\n To build the system, a team led by RQC scientist Kirill Lakhmanskiy developed specialized laser equipment and a complex optical structure. This setup allows for accurate control of quantum states and the execution of fundamental logical operations.<\/p>\n The processor achieved record accuracy levels for a quantum system of this size: 99.92 percent for single-qubit operations and 96.5 percent for two-qubit operations.<\/p>\n Lakhmanskiy stated that the team plans to use the new computer to run algorithms for combinatorial optimization, which are widely used in network design and complex logistics planning.<\/p>\n<\/div>\n
