Our paper with Yoshihiko Hasegawa is out in Phys. Rev. E. We show quantum computers as unique testbeds for thermodynamic trade-offs, validating and saturating a general quantum thermodynamic uncertainty relation (a cost-precision bound) for the first time. link.aps.org/doi/10.1103/9x…

Accepted to NeurIPS'26. It was a great collaboration during my one-year stay in Zuse Institute Berlin. Now I'm returning to Japan.

Our paper on the inverse Thermodynamics Uncertainty Relation has appeared in PRL! If you're a fan of TUR, I think you'll like the iTUR concept. Prof. Saito is giving a talk about it next Monday at YITP. More results coming soon! journals.aps.org/prl/abstract/1…
