Fudan University Approved for China's First "Fusion Science and Engineering" Interdisciplinary First-Level Doctoral Degree Program

Recently, Fudan University's "Fusion Science and Engineering" interdisciplinary first-level doctoral degree program was officially approved, making the university the first higher education institution in China to establish such an interdisciplinary first-level doctoral degree program. The degree program is led by the Institute of Modern Physics (Department of Nuclear Science and Technology), and will officially begin doctoral student admissions in 2026. Currently, global fusion R&D is transitioning from the stage of scientific exploration to the critical period of engineering verification and commercialization. China's "15th Five-Year Plan" recommendations list fusion energy as a new economic growth point for future industries. Accelerating the cultivation of high-level fusion talent has become an urgent task for safeguarding national energy security and seizing the high ground of future science and technology industries.

Fudan team extracts CKM matrix element |Vus| via quantum entanglement in collider experiment for the first time

On the evening of September 2, 2026, Beijing time, the team led by Luo Tao from the Institute of Modern Physics at Fudan University, together with collaborators, published a research achievement titled "Exploring baryon semileptonic decays through polarization and entanglement" in Nature. This study, for the first time in a collider experiment, utilized quantum entanglement and polarization information to extract the Cabibbo-Kobayashi-Maskawa (CKM) matrix element |Vus|, providing a new experimental pathway for precisely testing the Standard Model of particle physics. The CKM matrix describes the strength of transitions between different quarks under the weak interaction. Among them, |Vus| corresponds to the transition from the strange quark to the up quark, and its numerical precision is related to the test of the three-generation quark mixing mechanism in the Standard Model. Currently, results for |Vus| obtained from different decay processes still show discrepancies, and the unitarity test of the first row of the CKM matrix also exhibits some tension, necessitating more independent measurement methods for verification.
