2025 May | Our work that introduced a quantum extenstion of dynamic programming has been published in Physical Review Letters. Joint work with Jeongrak Son, Marek Gluza, and Nelly Ng at Nanyang Technological University Singapore. |
2025 May | Work by Yosuke (who was with us until this March) on random unitaries has been published in Physical Review Letters and Physical Review A. |
2025 Apr | Our work on quantum thermodynamics has been published in Physical Review Letters. We showed that “Gibbs-preserving operations”—one of the standard operations frequently used in anslysis—may incur infinite costs to implement, prompting us to reconsider the physical justification of their use. Joint work with Hiroyasu Tajima at Kyushu University. |
2025 Apr | Posted a preprint (by Kaito and Ryuji) on quantum thermodynamics. 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. |
2025 Apr | Hayato, two Koki’s, Rio, and Shinnosuke have joined the group. Welcome! Yosuke has moved to RIKEN. Best of luck with the new position! |
2025 Mar | Our work (by Yosuke and Ryuji) on the noise purification of quantum channels has been posted on arXiv. Joint work with Kento Tsubouchi and Nobuyuki Yoshioka at the University of Tokyo. |
2025 Feb | Our work (by Oliver and Ryuji) on the connection between magic and non-Gaussianity has been published in PRX Quantum. Joint work with Giulia Ferrini at Chalmers University of Technology. |
2024 Dec | Ryuji gave a three-day lecture series at Kyoto University on qunatum resource theories and quantum error correction. |
2024 Dec | Paper by Kaito and Ryuji has been published in Physical Review Letters. Press release (in Japanes) is here. |
2024 Dec | Works by Yosuke (arXiv:2410.24127, arXiv:2411.04766) and Ryuji (arXiv:2404.03479) have been accepted as talks at QIP 2025 conference. |
2024 Oct | Oliver has joined the group. |
2024 Aug | Takeru has received a silver prize of the student poster award at the Asian Quantum Information Science Conference (AQIS2024) conference. |
2024 Apr | Our group has been launched. Cheepin, Kaito, Takeru, Yosuke have joined the group. |
2023 Apr | Takagi has moved to UTokyo. |
