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.

Sweden's First New Nuclear Reactor Could Be Operational by Mid-2030s

Sweden's Minister for Energy and Industry, Ebba Busch, who also leads the Christian Democrats (KD), stated at a public hearing on September 3 that the country's first newly built nuclear reactor could be operational by the mid-2030s. When asked when the new nuclear unit could be connected to the grid, Busch indicated the mid-2030s. She also noted that the new nuclear project would not rely on direct state funding. However, the Swedish government has previously prepared a support framework for new nuclear construction. The arrangements could involve financial support amounting to hundreds of billions of Swedish kronor, including loans and electricity price guarantees totaling approximately 400 billion Swedish kronor. Busch stated that this is indeed a substantial sum, but its nature is that of loans and price hedging arrangements targeting critical infrastructure.

Russia Plans to Build Floating Nuclear Power Plant Production Facility Near Murmansk

Rosatom is considering building its own production facility near Murmansk to complete the construction of floating nuclear power plants. The company believes that as related orders increase, the capacity of existing partners may struggle to meet future demand. Baltic Shipyard is one of Rosatom's key partners. The Akademik Lomonosov floating nuclear power plant and four Project 22220 Arktika-class nuclear-powered icebreakers were all built at this shipyard. Currently, the two sides continue to maintain close cooperation, with a significant portion of Baltic Shipyard's orders related to Rosatom projects. Russia...

Hungary's Paks II Nuclear Project May Require Major Adjustments

According to sources familiar with Hungary's nuclear industry and discussions on the Paks II nuclear project, the new Hungarian government led by Peter Magyar believes that the Paks II project, based on Russia's Rosatom design, can only proceed if major adjustments are made. Sources said that due to factors such as ethics, technology, sanctions restrictions, licensing procedures, and existing contract terms, the Paks II project is difficult to continue under its original arrangement. However, industry insiders also believe that it would not be appropriate to abandon the project outright due to short-term sentiment or temporary setbacks. If more participants could be brought in,...
