New paper on arXiv: scirate.com/arxiv/2603.120… We showed that all sets of star-incompatible measurements are useful for steering-based (one-sided device-independent) randomness certification. Joint work with @quaintum

New paper: scirate.com/arxiv/2605.119… We showed that a tradeoff of the accuracy for any joint realization of two incompatible channels is bounded by the generalized robustness of incompatibility. This provides an error-error and information-disturbance tradeoff in a unified manner.

Congratulations!

We will hold the workshop "Quantum Foundations" from March 5, 2026 to March 6, 2026 at The University of Osaka (Toyonaka): qsys.se.shibaura-it.ac.jp/kimura/QFound/… So far, this workshop has been held as a hybrid of on-site and online, with most sessions in Japanese, but one in English.

Next week, I will be around Tokyo. The week after next, I will be in Kyoto. After that I will be in Osaka.

2025年9月8～12日京都大学基礎物理学研究所にて、量子力学100周年を記念する量子基礎・量子情報をテーマとする研究会を行います！ ・招待講演のみ ・参加登録、ポスター発表：7月18日締切 ・学生旅費補助：7月4日締切 詳細情報はこちらから：indico.yukawa.kyoto-u.ac.jp/event/64/ 皆様、奮ってご参加ください！

I became a postdoctoral researcher at Aix-Marseille Université in France.

On march 25th, 2025, I received my PhD from Nagoya University and on April 1st, 2025, I became a postdoctoral fellow at University of Tsukuba

A paper with Slovak Academy of Sciences on the consistency between Maxwell's demon with operationally permissible general measurements and feedback control and the second law of information thermodynamics has been published in npj Quantum Information nature.com/articles/s4153…

We have renewed our group website! math.mi.i.nagoya-u.ac.jp/~qmathinfo/

@qJosepLumbreras from Centre for Quantum Technologies, National University of Singapore visited us this week and gave us a very interesting seminar on quantum bandits. Thank you very much!

Bell定理の研究会いよいよ来週9/3(火)です．参加申し込みの締め切りが9/1と迫っています：qsys.se.shibaura-it.ac.jp/kimura/Bell60/… おかげさまで多くの方（150名超）の申し込みをいただきましたが，現地参加があまりふるってないので，ぜひ関東近辺の方はご検討を！！

Successfully arrived in Sapporo

The weather in Nagoya is sometimes heavy due to the typhoon. I wonder whether I will make it to Sapporo tomorrow night and attend one of the AQIS satellite workshops... sites.google.com/elms.hokudai.a…

I am very happy to have had the opportunity to participate in this wonderful conference. I would like to thank the organizers and everyone who made many interesting presentations and discussions.

Thanks to all our conference participants for letting us take this lovely photo of you all! Still a conference dinner and two fun-filled days to go here at @tcddublin @TCD_physics

Ready to go!

Just arrived at Trinity College, looking forward @EoC24Conf
