4th International School of Quantum Technologies

PHOTO ALBUM QTS’21

Report on the 4th International School of Quantum Technologies (QTS’21)

The 4th international school on quantum technologies was held in the conference hall of the in the Voronovo settlement (New Moscow) from November 9 to 12, 2021.

The QTS’21 was attended by 81 people (17 lecturers, 9 speakers and 55 students, of which 17 people participated in the poster section). The School delivered 17 lectures on quantum computing, quantum optics, quantum cryptography and quantum technologies, 8 reports on the practical use of quantum technologies. Foreign lecturers delivered their lectures online.

Video recordings of lectures are available on the YouTube channel.

In addition to students, graduate students, and employees of scientific organizations, representatives of commercial organizations also participated in the work of the School: Infotecs, LLS, Concept Expert, ETM Photonics.

Демо стенды по квантовой криптографии

Во время работы Школы желающие ознакомились с принципами работы двух демо стендов.

Взлом детектора одиночных фотонов

Демо показывает, как тестировать детекторы одиночных фотонов на атаку ослеплением в лабораторных условиях. Если детекторы могут быть ослеплены, то система квантовой передачи ключа, использующая такие детекторы, не может считаться надежной (мы покажем, почему) [1]. Несмотря на то что атака известна уже более 10 лет, эта лазейка в защите до сих полностью не закрыта.

Волоконно-оптическая система квантовой передачи ключа

Демо показывает оптическую схему квантовой передачи ключа с автокомпенсацией (или так называемой «plug-and-play») [2]. Вы увидите, как выполнены процедуры временной и прочих калибровок для достижения надлежащей синхронизации сигналов между Алисой и Бобом.
