摘要:

ATLAS合作组近期报告了在大型强子对撞机(LHC)上首次观测到顶夸克对产生过程中的量子纠缠。本文简要回顾了顶夸克对自旋关联的实验研究现状,随后重点阐述了经典关联与量子关联之间的预期差异。研究提出了一种用于检测顶夸克对中自旋纠缠的判据,讨论了实现该判据并观测该效应的实验策略,同时展示了ATLAS测量得到的正面结果。

英文摘要:

The ATLAS Collaboration has recently reported the first observation of quantum entanglement in top quark pair production at the Large Hadron Collider (LHC). A brief review of the experimental status of top quark pair spin correlations is given, before highlighting the expected differences between classical and quantum correlations. A criterion for the detection of spin entanglement in top quark pairs has been proposed; the experimental strategy to implement it and observe the effect is discussed, and the positive results of the ATLAS measurement are presented.
