2025: Product Announcement
In May 2025, the Shukhov.Nano Nanotechnology Center, created by the Moscow State Technical University named after N.E. Bauman and FSUE VNIIA named after N.L. Dukhova, presented the iDEA technology for the manufacture of quantum processors with sub-angstrom accuracy (angstrom ±0,2, where 1 angstrom is 0.1 nanometers). The new development will allow serial production of quantum processors with thousands of qubits - superconducting artificial atoms with precisely specified parameters.

As the developers explain, iDEA (ion beam-induced DEfects Activation) technology provides unprecedented accuracy in the formation of qubit elements based on tunnel dielectrics 0.8-2 nm thick with an error of only ±0,02 nanometers. This is an order of magnitude superior to traditional methods of manufacturing quantum processors and paves the way for the creation of practically useful hybrid supercomputers. The results of the study are published in the journal Science Advances, and the technology itself is protected by a Russian patent and is undergoing international patenting.
The principle of operation of the iDEA is to control the thickness of the tunnel dielectric of the qubit by irradiating ions of inert gases. During irradiation, defects are generated in the crystal lattice, which provoke an ultra-accurate change in the thickness of the selected metal-oxide interface, which is critical for the practical use of quantum computers.
The head of the Quantum Park cluster, Ilya Rodionov, notes that previously only nature, not technology, could create the same atoms. Even the slightest variation in size in ±5 nm or the thickness of the tunnel barrier in the fraction of a nanometer led to unacceptable errors for some qubits. According to him, a quantum processor is a single mechanism that combines a dozen advanced technologies, and the presented method of controlling qubit parameters opens the way to practically useful quantum computing.
