Summary
[edit]DescriptionQuantum metamaterial with 24 artificial atoms.png |
English: SEM image of a quantum chip composed of an array of 24 artificial atoms (aluminum qubits). Here, you can consider the key architectural elements of superconducting devices: transmon qubits based on sub-100nm Josephson Junctions, microwave coplanar resonators, and superconducting airbridges to equalize the electric potential of the ground over the entire area of the quantum circuit. Atoms interact with each other through the resonator and their spontaneous emission can merge into one short powerful pulse (Dicke model).
In order to create such quantum circuits, FMN Laboratory has developed unique multilayer technologies including hundreds of technological operations and bringing the parameters of these devices at the level of the best world analogues. Today, the results of this work allow dozens of leading Russian scientists to carry out complex experiments aimed at developing a Russian quantum computer.
Русский: Квантовый метаматериал из 24 искусственных атомов
Электронное изображение квантового чипа, состоящего из массива 24 искусственных атомов (алюминиевых кубитов). На схеме можно рассмотреть ключевые элементы архитектуры подобных сверхпроводниковых устройств: кубиты-трансмоны на основе суб-100нм Джозефсоновских переходов, сверхвысокочастотные копланарные резонаторы, а также сверхпроводящие «воздушные мосты» для выравнивания электрического потенциала земли по всей площади квантовой схемы. Атомы взаимодействуют через резонатор друг с другом, и их спонтанное излучение способно сливаться в один короткий мощный импульс (модель Дикке). Для создания таких квантовых схем в НОЦ ФМН разработаны уникальные многослойные технологии, включающие сотни технологических операций и обеспечивающие параметры этих устройств на уровне лучших мировых аналогов. Сегодня результаты этих работ позволяют десятками ведущих ученых России проводить сложнейшие эксперименты, нацеленные на разработку российского квантового компьютера. |
