Posted a joint work with Naoto Shiraishi on quantum thermodynamics. We managed to characterize the state transformability (for general coherent states!) with a correlated catalyst by the single free energy ordering. arxiv.org/abs/2510.05642

The next quantum resources workshop happens in Tokyo! Looking forward to seeing many of you there! 2026.quantumresources.science Submission deadline: 31 October 2025 Workshop: 16–20 March 2026

Posted our work on Uhlmann transformation, where we provided its algorithmic implementation. As an application, we improved on the prior state-of-the-art cost for fidelity estimation in purified access model. Joint work with Takeru Utsumi, Yoshifumi Nakata, and Qisheng Wang. arxiv.org/abs/2509.03619

Our paper (w/ Marek, @ryujitakagi.bsky.social, @nellynghy.bsky.social ) on Quantum Dynamic Programming has recently been published in PRL: journals.aps.org/prl/abstract... Xin Yi from CQT wrote a great highlight article for this paper: www.cqt.sg/highlight/20...

Our work on quantum thermodynamics has been published in PRL. We showed that Gibbs-preserving operations may incur infinite costs to implement, prompting us to reconsider the physical justification of their use. Joint work with Hiroyasu Tajima. journals.aps.org/prl/abstract...

Posted a preprint with @kaitowatanabe.bsky.social on quantum thermo. We introduced a "universal work extractor", which is designed independently of the input state but still extracts the optimal work from every input state given in the iid form. arxiv.org/abs/2504.12373

Kaito Watanabe "Black box work extraction and composite hypothesis testing" #QuantumResources2025 Glad to learn about these results. I'll likely adapt my talk for Thursday a bit based on what I learned.
