Last week, the 26th edition of the Conference on Quantum Information Processing (QIP) took place in Ghent, Brussels. Established, without doubt, as the most important conference on the theory of quantum information and computation, this year QIP gathered over 700 participants, from world-leading experts to young master and PhD students. Compared to the 2014 edition in Barcelona (the first one I attended), the number of participants has almost doubled, reflecting the amazing growth that the field has had in the last decade.

As promised in our last post, I was there in Ghent to present some recent results on the quantification of quantum randomness. The attendance to the poster session was the largest I have recollection off (the free Belgian beer offered might have contributed to this). I am quite satisfied with the reception that the results had and the discussion that they sparkled. It is always rewarding to see that our research directions are supported by the community.

There were several interesting talks and posters this year. Luckily, the former will be uploaded to the conference’s YouTube channel for everybody to see. Readers interested in quantum cryptography (as we are) shouldn’t miss, amongst others, Tony Metger explaining the generalized entropy accumulation theorem and Yu-Chen Shen talking about better second order rates for privacy amplification.

All in all, QIP2023 was a fantastic event, with lots of opportunities for networking in an ever growing and vibrant community.
