News Summary:

On January 5, the Institute for Quantum Optics and Quantum Information — Vienna (IQOQI-Vienna) of the Austrian Academy of Sciences announced on its official website the winner of the 2021 Paul Ehrenfest Best Paper Award for Quantum Foundations. The paper "Proof of the Peres Conjecture for Contextuality" by Chinese scholar Dr. Zhen-Peng Xu, Prof. Jing-Ling Chen from Nankai University, and Prof. Otfried Gühne from University of Siegen, Germany, became the only winner of the award. It is awarded for "proving a long standing conjecture concerning the minimal construction that can be used in a proof of the Kochen-Specker theorem." The paper was published in Physical Review Letters in June 2020. It is reported that this is the first time that the award has been given after two years of interruption in 2019 and 2020.

Zhen-Peng Xu, the first author of the paper, was a Ph.D student at the Theoretical Physics Division of Chern Institute of Mathematics, Nankai University in 2013-2018, and currently a postdoctoral fellow in the research team of Professor Gühne under the support of Alexander von Humboldt Foundation. Jing-Ling Chen is a professor at the Theoretical Physics Division of Chern Institute of Mathematics, Nankai University, and his research focuses on quantum physics and quantum information. Their program is supported by the National Natural Science Foundation of China (NSFC).
