Event Review: The Second Quantum Connections Winter School

Held from January 4 to 17, the Second Quantum Connections Winter School emerged as a landmark academic gathering in the field of quantum science, bringing together world-renowned physicists, emerging researchers and young scholars for two weeks of immersive lectures, dynamic Q&A sessions, insightful poster presentations and a special memorial session honoring the legacy of Prof. C. N. Yang. Hosted via the platform quantum-connections.net, the event spanned academic exchanges, knowledge sharing and cultural interactions, solidifying its role as a pivotal bridge for global quantum science collaboration.

The winter school kicked off on January 4 with arrival and registration, setting the stage for a packed academic agenda that officially commenced on January 5 with a grand opening delivered by Nobel laureate Frank Wilczek—an iconic figure who remained a core contributor throughout the event. The first week featured a rigorous schedule of back-to-back lectures by leading experts, with Hans Hansson and Maxim Gorlach kicking off the academic talks on the opening day, followed by in-depth Q&A sessions that fostered real-time intellectual dialogue between speakers and attendees. A key highlight of the first week was the dual poster sessions (January 5 and 7), which provided a vital platform for early-career researchers to showcase their work, exchange ideas and receive feedback from established scholars in the field. Daily lecture series were led by distinguished scientists including Maxim Chernodub, Ye Wang, Markus Aspelmeyer, Qihang Liu, Steven Simon and Hong Ding, each delivering two consecutive hours of lectures (interspersed with 15-minute breaks) that delved into cutting-edge quantum science research directions and breakthroughs. The first week concluded with an excursion on January 10, offering participants a chance to unwind and build informal academic connections outside the lecture hall.

The second week elevated the academic discourse with deeper dives into specialized quantum science topics and a highly anticipated Special Session in Memory of Prof. C. N. Yang on January 13—the emotional and academic centerpiece of the winter school. This dedicated session featured a stellar lineup of speakers from across the globe, blending pre-recorded talks, online presentations and in-person lectures to pay homage to Prof. C. N. Yang’s unparalleled contributions to physics. Mo-Lin Ge presented a video talk titled C. N. Yang and Physics in China, tracing Prof. Yang’s profound influence on the development of physics research in China, while Li Hua Yu shared personal insights online in How Prof. Yang influenced my research interests and my current work, highlighting his mentorship to generations of researchers. Frank Wilczek delivered a compelling lecture on Parity Violation, a topic closely linked to Prof. Yang’s groundbreaking work, followed by Xiwen Guan’s discussion on the Yang-Baxter equation—a cornerstone of mathematical physics named in part for Prof. Yang. The session also featured frontier research talks, including Jianwei Pan’s Quantum Network: Quantum communication, computation, and metrology, Antti Niemi’s exploration of Yang-Mills Theory and Yu Shi’s analysis of C. N. Yang’s Physics, collectively painting a comprehensive picture of Prof. Yang’s legacy and its enduring impact on modern quantum science.

In the days following the memorial session (January 14–15), the winter school continued its lecture series with talks by Qihang Liu, Mairi Sakellariadou, Chaoyang Lu, Pavel Belov and Maxim Gorlach, each session followed by targeted Q&A that encouraged critical thinking and in-depth discussion of technical details. Every lecture block was thoughtfully structured with coffee breaks and lunch intervals, ensuring a balance between intense academic learning and rest for participants.

The winter school drew to a close on January 16 with a series of cutting-edge short talks by emerging researchers, covering innovative topics such as generalized axion response, bosonic Josephson junctions, density matrix geometry, exchange statistics in phase space, infinite temperature quantum phases and the interaction of twisted light with free atoms. These talks underscored the vitality of young talent in quantum science and the event’s commitment to nurturing the next generation of researchers. The formal academic program concluded with a closing remark at 17:15, followed by a warm departure banquet that celebrated the two weeks of collaboration and learning. The event officially ended on January 17 with participants’ departure, marking the conclusion of a transformative academic journey.

A defining strength of this winter school was its global and interdisciplinary faculty lineup, featuring leading physicists from diverse research backgrounds—from quantum theory and quantum communication to condensed matter physics and mathematical physics. The seamless integration of long-form lectures, interactive Q&A, poster sessions and themed memorial events created a multi-dimensional learning experience, catering to both in-depth knowledge acquisition and informal academic exchange. The special session for Prof. C. N. Yang added a profound historical and cultural layer, linking the latest quantum science research to the field’s foundational legacy and inspiring attendees with the spirit of scientific exploration embodied by Prof. Yang.

Beyond academic knowledge transfer, the Second Quantum Connections Winter School successfully built a global network of quantum science researchers, fostering cross-border and cross-institutional collaboration. The event’s careful scheduling—balancing rigorous academic activities with social and cultural events—ensured that participants not only expanded their professional knowledge but also forged lasting connections with peers and mentors from around the world. As a premier academic event in quantum science, it set a high bar for future winter schools, providing a model for immersive, inclusive and impactful scientific exchange.

In summary, the Second Quantum Connections Winter School was a resounding success, serving as a global hub for quantum science knowledge sharing, talent cultivation and collaborative networking. It not only showcased the latest breakthroughs and research directions in quantum science but also honored the legacy of scientific pioneers, inspiring the next generation of researchers to push the boundaries of quantum science exploration. The event’s achievements will undoubtedly resonate in the global quantum science community, driving further collaboration and innovation in the years to come.
