Russian specialists from MSTU named after N. E. Bauman and FSUE “VNIIA N. L. Dukhov” developed a new technology for creating quantum systems on a crystal, which allows you to combine quantum accompaniment and reading systems on a single chip. The development was reported in the press service of the Ministry of Education and Science of the Russian Federation. The technology is aimed at increasing the accuracy of quantum algorithms and a significant decrease in the size of the element base.
Technology is successfully applied in creating parametric cryogenic amplifiers of a new generation. These devices provide information from multi -cubic quantum processors with a minimum noise level. According to developers, the sizes of amplifiers are reduced by more than 300 times – to several hundred micrometers.
The authors of the technology use a design based exclusively on microscopic elements: plane -parallel capacitors and planar inductance coils. This made it possible to significantly improve the parameters of the device. For example, the amplifier has an amplification coefficient of more than 15 dB, a wide bandwidth of about 600 MHz and the noise temperature of the system up to 350 Milkelvin. The results are published in the magazine Applied Physics letters .
In order to achieve such characteristics, innovative materials were used, including dielectrics with ultranide losses based on amorphous hydrogenated silicon. These materials reduce noise level, which is critical of working with quantum processors. Scientists note that the created technology is a comprehensive development that includes design methods, production and experimental assessment at cryogenic temperatures.
According to the rector of MSTU Mikhail Gordin, work on the project required refusing previous technologies and many years of developments. This made it possible to create systems on crystal, which in the future can provide accurate performance of almost useful quantum algorithms and accelerate the development of hybrid quantum-classic computers.
The new technology, according to scientists, brings the appearance of compact and energy -efficient quantum systems that will be in demand in cryptography, complex modeling and high -precision calculations.
