We have received a report from Eduard who has completed his internship in our lab! Thank you very much for your hard work over the three months from February to May.
当研究室でのインターンシップを終えたEduardさんから、レポートが届きました！2月から5月までの約3ヶ月間、お疲れ様でした。

When Prof. Sylvain de Léséleuc offered me an internship while meeting on a conference in Germany, I did not expect that this would become reality so soon. I was expecting to get to know a completely different culture and a new approach on Rydberg interactions, but these expectations where highly exceeded. After arriving, I received a very warm and friendly welcome, and was introduced to a very polite, honest, reliable and thankful team. The topic of Rydberg interactions after pulsed laser application was new to me, and it was great to learn so fast so much about it, and quantum computing in general. I especially enjoyed the Journal clubs, where we discussed cutting-edge progress in the large field of quantum computing. There was not a single Journal club in which I did not learn something new. In addition, I was astonished how well the different research teams in Japan are connected, cross-collaborating through different research areas, including even solid-state laser physics. In particular, I loved the seminars that allowed to get insights in state-of-the-art research both in academic research as well as in quantum start-ups, whilst having the opportunity to ask questions directly to the principal investigators and CEOs. Besides the great work atmosphere, I also got fond of the common lunch breaks and dinners, where I had the opportunity not only to get introduced to the amazing taste of the Japanese cuisine, but also to learn some Japanese, Hindi, Bengali, Thai and many other languages with my fantastic colleagues from all over the world. Notably, I will always keep the group Hanami party in good memory.

As far as my project is concerned, I was working both theoretically as well as experimentally on microwave dressing of an ultrafast Rydberg gate. Using my experience with arbitrary waveform generators in Heidelberg University, I liked setting up a system creating microwave radiation with controllable polarization using a quadrupole antenna. It was also a fascinating challenge to write my own driver for the signal generator, and to learn what really happens once a device is plugged into a USB port. For the theory part, I enjoyed writing a code based on the Floquet theorem in order to calculate the time evolution of two atoms initialized in a certain Rydberg state under the influence of a microwave drive. To conclude, I had a great time, an outstanding team, I learned a lot, and loved my project. I definitely recommend this group, if you are looking for an internship in Japan, and miss the people there already now. And don’t forget to also take a walk to Mount Fuji!
