Snowdrop 4Q (quantum processor)

2024: Product Announcement

Russian scientists presented the latest quantum processor, which demonstrated record performance of algorithm execution accuracy. This became known on June 25, 2024. The processor was developed at the scientific and educational center "Functional Micro/Nanosystems" on the basis of the Moscow State Technical University named after N. E. Bauman and the All-Russian Research Institute of Automation (VNIIA) named after N. L. Dukhov. According to the institute's experts, this processor has opened up new possibilities for the practical application of quantum computing.

According to Izvestia, the new superconducting quantum processor is called Snowdrop 4Q. The device includes a chip based on four qubits, signal reading modules and control electronics units. The accuracy of simple single-bit operations on the processor was 99.76%, and two-bit operations - 99.11%.

These parameters are a record for Russia and are comparable to the best world achievements. For example, in the IBM Torino 133 processor with Heron R1 architecture, the average accuracy of two-bit operations is 99.14%. Russian scientists, using Snowdrop 4Q, were able to solve complex equations such as the Ising model and the thermal conductivity equation, which confirms the high efficiency of the new device.

Nikita Smirnov, a leading developer of quantum processors at the Scientific and Educational Center, noted that the accuracy of logical operations achieved on the Snowdrop 4Q processor made it possible to execute a series of complex algorithms. He stressed that calibration and full characterization of the quantum system took three months. "The best test for a processor is to run a complex algorithm on it using all available qubits, which we did," Smirnov said.^[1]
