BEC is a prestigious conference on quantum gases and related fields which happens biannually. This conference provides an outstanding scientific platform for researchers to share their latest developments in the field.BEC 2023 takes place in Sant Feliu de Guíxols (Spain) at the Hotel Eden Roc from Saturday, September 9th to Friday, September 15th, 2023.

The total number of participants in the BEC 2023 conference was around 200 which includes 40 outstanding invited speakers such as Antoine Browaeys, Institut d’Optique CNRS; Adam Kaufman, JILA ; Waseem Bakr, Princeton University; Mikhail Lukin, Harvard University;Wolfgang Ketterle, MIT; Immanuel Bloch, Max-Planck-Institute of Quantum Optics & LMU Munich; Tilman Pfau, University of Stuttgart; Markus Oberthaler, Heidelberg University,… etc. and 145 researchers who presented their recent results by the poster presentation.

The conference programme was organized in five sessions of which 4 sessions were dedicated to the invited talks for 35 minutes for each speaker and 2 talks per session. The poster session was the fifth session which started after dinner from 9:00 pm to 11:00 pm.


There were many recent developments in the field of quantum computation and simulations were presented by the researchers.
A few of them are as follows:
•Demonstration of two qubit-highest fidelity gate operations (by Mikhail Lukin, Haward University), Tunable arrays of individual Rydberg atoms, light-induced interactions of an atomic ensemble,  light-induced interactions in the Dy (Dysprosium,rare Earth element) atom (by Antoine Browaeys).
•The exciting results of the Microscopy controlled arrays of Alkaline-earth atoms (at the single atom level control) and the demonstration of the platform of the neutral atom (88Sr) quantum simulation by utilizing the Programmable Hubbard system(by Adam Kaufman, JILA ).
•There was a very exciting result of the quantum field simulator in which it was demonstrated how one can use the system of a two-dimensional potassium gas to simulate the dynamics of a scalar field in time-dependent curved spacetime. Very Exciting for me to see that Einstein’s field equation was utilized for the quantum simulation (by Markus Oberthaler, Heidelberg University). 
•Demonstration of the two-qubit gate with the fidelity of .993 ± 0.001(Science, 369,550(2020)) for entangling 1250 atom pairs by using a 2D lattice of 87Rb. The atomic preparation is similar to our setup only difference is in the single-site imaging by using the quantum gas microscope by which they imaged the atoms with ~577nm resolution (Jian-Wei Pan, University of Science and Technology of China, Hefei, Anhui230026, China).


Poster session:  Poster session was very fruitful for me. There were many discussions during the poster session with researchers related to current developments in the field of quantum simulation and computation.
My poster was found to be unique from all other posters in the sense that we have demonstrated the platform of the ultrafast Quantum simulation by combining the ultracold atomic platform with ultrafast technology.  This point was highlighted by Prof. Robert Spreeuw, Prof. Dr. J.T.M. Walraven who visited my poster.   Other visitors to my poster include Prof. Peter Hommelhoff, Dr. Andrei Sidorov, Dr. Peter Schauss, Prof. Dr. Tilman Esslinger, Prof. Dr. Philipp Treutlein, Dr Mehedi Hasan, Dr. DANSHITA Ippei and Shion Yamashika. There was a good discussion and also an appreciation of all of them. There was a long discussion with the Prof. Dr. J.T.M. Walraven about our results and procedure and after the discussion he was impressed with the result and during the photo he highlighted Ohmori-sensei and Prof. M. Weidemüller.


TOPTICA BEC Award 2023 and Excursion to the Cruize:  BEC awards honour outstanding research in Experimental and/or Theoretical  Physics of Quantum Degenerate Atomic Gases.  There are three prizes of the BEC award.
The Senior Prize: This prize recognizes the specific work that is firmly established and has  significantly advanced the field of Quantum degenerate gas. The BEC 2023 Senior Prize was awarded to  Prof. Tilman Pfau for his “pioneering experiments on long-range interacting quantum gases of dipolar atoms and Rydberg excitations”.
The Junior Prize: This prize recognizes outstanding work by a young scientist for research early in her/his academic career. The BEC 2023 Junior Prize was awarded to Dr. Monika Aidelsburger. 
Award for lifetime achievements: This prize recognizes a longstanding important contribution to the field. The BEC 2023 lifetime award was given to Prof. Alexander Fetter and Prof. Wilhelm Zwerger “for their individual foundational theory works on quantum Many-body physics and superfluidity of ultracold gases”.

Overall, the conference was great and very fruitful for me. I got the opportunity to interact with great researchers in the field and get motivated by the exciting results. Finally, I would like to thank Ohmori-sensei for his permission to attend the conference. I am also thankful to Sylvain-san for his suggestion to attend this great conference and relevant discussions. It would have not been possible to attend the conference without the help of Sakai-san, Koshida-san, Kawamoto-san and Nishioka-san.I thank all of them for their help and support. I would also like to thank the other group members for their help and discussion.
