Newly published in Quantum: Mixed-state additivity properties of magic monotones based on quantum relative entropies for single-qubit states and beyond by Roberto Rubboli, Ryuji Takagi, and Marco Tomamichel doi.org/10.22331/q-202…

Missed the QIP deadline? Don't fret. You still have two weeks to submit your work to the Quantum Resources workshop, taking place in Korea next March!

I'm looking to hire a postdoc interested in the more Shannon-theoretic aspects of quantum information. Come work with me in Japan! Starting date can be ASAP and should be within the first half of 2025. See bartoszregula.me/recruitment or the official ad at riken.jp/en/careers/res…

[プレスリリース] 量子熱力学の仕事の取り出しと複合量子仮説検定の根源的な関係を解明――総合文化研究科・教養学部 u-tokyo.ac.jp/focus/ja/press…

研究室の渡邉開人さん(Kaito Watanabe)との共同研究が出版されました。与えられた量子状態の集合から選ばれた未知の状態から取り出せる仕事を、複合仮説検定の問題に落として特徴づけました。ご興味ある方はぜひご覧ください！

Joint work with my student Kaito Watanabe on work extraction from an unknown quantum state has been published. See Kaito's concise summary on this!

(1/10) Here's a 🧵with my own personal year-in-review for quantum thermodynamics summarising some of my favorite results from 2024. I'm sure I'll miss many things but for a field which quite a few scientists claim is dead so very many cool results were achieved this year. Feel

Our unit OIST is hiring two postdocs, one lab manager/technician, and one field technician! If you're passionate about exploring microbial and ecosystem ecology at the international institute on this beautiful island, please apply by April 20!🍄🦠🌳🌞 oist.jp/research/resea…

New work on "Symmetric Channel Verification," a general framework lifting (virtual) error detection and correction to channel level. Prominently, it breaks barrier of existing QEM; symmetry-breaking noise under arbitrary input states. Congrats Kento! arxiv.org/abs/2503.13114

研究室修士学生の渡邉さんKaito Watanabe との共同研究をポストしました。量子熱力学における仕事の取り出しにおいて、これまで知られていた最適なプロトコルは状態の情報に依存したものでしたが、この論文では全ての状態から最適な仕事を取り出せる"universal work extractor"を提案しました。

Posted a preprint with Kaito Watanabe on quantum thermo. We showed that the optimal work can be extracted by a thermal operation independent of input state, as long as the unknown input state is given in the iid form.

PRL version now out! journals.aps.org/prl/abstract/1… A major update from the first arXiv version: we show that numerous state transformations are impossible under any finite-cost Gibbs-preserving operation, yet become achievable once the cost is allowed to diverge.

東大の高木さんRyuji Takagiとの共同研究がPRLから出版されました。コスト無限のGibbs保存操作が無限個存在することを、以前の結果である対称性・不可逆性・量子性のトレードオフから示しました。関連結果でQIPが3本出てるので、それらもツリーに載せています。ご興味があれば是非ご覧ください！
