近日，韩国西江大学的Wontae Kim及其研究小组取得一项新进展。经过不懈努力，他们对AdS2黑洞中的黑洞互补性进行研究。相关研究成果已于2024年2月21日在国际知名学术期刊《高能物理杂志》上发表。
该研究团队在二维反德西特黑洞的背景下进行了爱丽丝-鲍勃思想实验。实验结果表明，在大黑洞的情境下，信息克隆问题可以得到有效规避。具体来说，根据Hayden-Preskill准则，只要与一维重参数化群显式破缺相关的尺度参数明显大于黑洞质量的平方，就能够成功地避免信息克隆的发生。
据悉，黑洞互补性原理视霍金辐射为信息传递的媒介，在解决信息丢失悖论中起到了至关重要的作用。然而，从霍金辐射中提取信息的机制却异常复杂。Susskind和Thorlacius提出的思想实验，以及Hayden和Preskill所确立的标准，为人们深入理解了基准观察者与落入黑洞观察者之间复杂的互补性关系提供了重要见解。

Abstract: Black hole complementarity plays a pivotal role in resolving the information loss paradox by treating Hawking radiation as carriers of information, apart from the complicated mechanisms involved in decoding information from this radiation. The thought experiment proposed by Susskind and Thorlacius, as well as the criteria set forth by Hayden and Preskill, provide deep insights into the intricate relationship of black hole complementarity between fiducial and infalling observers. We execute the Alice-Bob thought experiment in the context of two-dimensional anti-de Sitter black holes. It turns out that information cloning can be avoided in the case of a large black hole. According to the Hayden-Preskill criteria, if the scale parameter associated with the explicit breaking of the one-dimensional group of reparametrizations is significantly exceed the squared mass of the black hole, then information cloning can be effectively evaded.
