Focussing on statistical issues, I will first sketch the history initiated by John Bell’s landmark 1964 paper “On the Einstein Podolsky Rosen paradox”, which led to the 2022 Nobel prize awarded to John Clauser, Alain Aspect and Anton Zeilinger,
A breakthrough in the history was the four successful “loophole-free” Bell experiments of 2015 and 2016 in Delft, Munich, NIST and Vienna. These experiments pushed quantum technology to the limit and paved the way for DIQKD (“Device Independent Quantum Key Distribution”) and a quantum internet. They were the first successful implementations of the ideal experimental protocol described by John Bell in his 1981 masterpiece “Bertlmann’s socks and the nature of reality”, and depended on brilliant later innovations: Eberhard’s discovery that less entanglement could allow stronger manifestation of quantum non-locality, and Zeilinger’s discovery of quantum teleportation, allowing entanglement between photons to be transferred to entanglement between ions or atoms and ultimately to components of manufactured semi-conductors.
I will also discuss reanalyses of the 2015+ experiments, which could have allowed the experimenters to claim even smaller p-values than the ones they published,

About the Speaker:
Gill是莱顿大学教授,著名统计学家,荷兰皇家科学院院士。Gill教授以开创生存分析中的计数过程方法而蜚声国际学界；也因为为营救因错误的统计分析而身陷囹圄的荷兰护士Lucia de Berk多方奔走，最终成功让荷兰最高法院改判无罪而赢得了社会广泛的推崇；Gill近十几年致力于推动量子统计的发展并取得了重要成果，例如，建立Bell’s theorem的因果理论和检验Bell inequality的统计方法，并被运用在首次成功的 “loophole free” Bell experiment. Gill 2019年10月曾受邀在北大统计科学中心讲授统计学与量子信息的短课，相关内容见
As a mathematician, probability theorist and statistician, Gill is most well-known for his research on counting processes and survival analysis, some of which has appeared in a widely used textbook. Gill is also known for his pro bono consulting and advocacy on behalf of victims of incompetent statistical testimony, including a Dutch nurse who was given a life sentence for serial murder; it took 9 years before it became clear that all deaths were “natural” but that doctors had made numerous errors, and lied about them to the courts, and her conviction was overturned. Gill is a pioneer in quantum probability and statistics. One contribution is the development of the statistical methods used to analyze the entanglement experiment in Delft.
