Summary

[edit]
Description
English: The FMN Laboratory team is assembling the cryogenic part of the quantum computer, which provides cooling of superconducting processors to almost absolute zero (-273.1°C). The chips of such processors are based on superconducting qubits and coplanar resonators operating at microwave frequencies. The qubit (“quantum bit”) – the driving force of a quantum computer – exhibits its unique properties only in conditions of absolute zero temperature and complete protection against external influences provided by the dilution cryostat. The scheme and construction of a measurement circuit, which includes hundreds of elements (control devices, special filters, and screens, attenuators, microwave components, etc.), largely influence the quality of the quantum systems we create.
Русский: Как измерить квантовый бит? Команда НОЦ ФМН в процессе сборки криогенной части квантового компьютера, которая обеспечивает охлаждение сверхпроводниковых процессоров почти до температуры абсолютного нуля (-273,1ºС). Чипы таких процессоров строятся на основе сверхпроводящих кубитов и копланарных резонаторов, работающих на сверхвысоких частотах. Кубит («квантовый бит») – движущая сила квантового компьютера – показывает нам свои уникальные свойства (то есть начинает «работать») только в условиях абсолютного холода и полной защиты от внешних воздействий, которые обеспечивает криостат растворения. Принципиальная схема и конструкция измерительной экспериментальной схемы, включающей сотни элементов (управляющие устройства, различные специальные фильтры и экраны, аттенюаторы, СВЧ-компоненты и т.п.), во многом определяет ключевые показатели качества создаваемых у нас квантовых систем.
