The 3rd international school on quantum technologies was held in the conference hall of the «Golden Tulip Rosa Khutor» hotel from March 1 to March 7, 2020. The hotel is located in the heart of the resort of Rosa Khutor (village of Esto-Sadok, Krasnodar Territory). The School was attended by 141 people (12 lecturers, 10 speakers and 119 students, of which 68 people participated in the poster section) from 7 countries (19 cities).
Distribution of participants by city:
In addition to students, graduate students and employees of scientific organizations, representatives of commercial organizations also participated in the work of the School. In total, 48 organizations were represented at the School:

The School delivered 12 lectures on quantum computing, quantum optics, quantum cryptography and quantum technologies, 11 reports on the practical use of quantum technologies, one report on the commercialization of quantum technologies (the program of the School).

Also, as part of the School’s program, three round tables were held. The topics of the first round table were quantum computing and quantum computers; N. Kolachevsky, E. Il’ichev, J. Biamonte, and P. Grangier answered questions from the audience.
 
The second round table was devoted to the commercialization of quantum technology products. The participants in the round table were A. Urivsky (InfoTeKS), S. Khanenkov (Rostelecom), P. Dorozhkin (Skoltech, Russian Railways), V. Makarov (RCC). The third round table on quantum cryptography was held in the form of an open discussion.
At the poster session, participants presented 68 reports (abstracts of poster presentations). The program committee of the School held a competition for the best poster presentations, the winners received prizes. List of winners:

1. Dmitry Moskalev (Bauman Moscow State Technical University) “Fabrication and characterization of near quantum-limited Josephson parametric microwave amplifier”
2. Benjamin Morris (University of Nottingham) “Entanglement between identical particles is a useful and consistent resource”
3. Murad Abuzarli (Laboratoire Kastler Brossel, Sorbonne Universite, CNRS, ENS-PSL Research University) “Superfluid light in dense atomic vapor”

All participants of the School received certificates and souvenirs.
Winter sport has traditionally been an important component of the School’s program. As part of the School’s winter sports program, 9 novice skiers and 9 snowboarders were trained, while the organizing committee paid half the basic cost of training, ski pass and equipment for beginners. Most skiers mastered the basic skills on the first day and on the other days rode on their own. Most beginner snowboarders were trained for two days.
