Quantum breakthrough: Russian scientists set a qubit “lifetime” record

As a result of the collaboration of scientists from the MSTU. N.E. Bauman and VNIIA them. N.L. Dukhov, a world record was set for the "lifetime" of superconducting qubits, which amounted to 50 microseconds. This discovery will further enable Russia to develop its own quantum computer, which will not be inferior to eminent world analogues.




Recall that the number of logical operations performed by a quantum computer directly depends on the “life time” of qubits. Thus, the first noise-resistant apparatus can be created by those researchers who can maximize the aforementioned indicator.

As stated "Izvestia" Ilya Rodionov, director of the REC REC FMN MSTU. N.E. Bauman, the result obtained by scientists is considered intermediate. The main goal of engineers is to develop a 100-qubit computing device with a “life expectancy” of discharge equal to 100 microseconds. In addition, at the moment, researchers clearly understand in which direction it is necessary to make improvements in order to achieve the aforementioned result.

Now in Russia a complex of serial of technologies in the field of quantum computing, where the development of crystals of quantum processors is already underway, and also a prototype module of a superconducting quantum computer has been created. In addition to Bauman University, they are involved in relevant research at NUST “MISiS”, Fiztekh and Chernogolovka. Financial support, in turn, is provided by the Advanced Research Foundation.
