报告摘要：Since the discovery of Hawking radiation, its consistency with quantum theory has been widely questioned. In the commonly described picture, irrespective of what initial state a black hole starts with before collapsing, it eventually evolves into a thermal state of Hawking radiations after the black hole is exhausted. This scenario violates the principle of unitarity as required for quantum mechanics and leads to the acclaimed information loss paradox, which has become an obstacle or a reversed touchstone for any possible theory to unify gravity and quantum mechanics. Based Hawking radiation as tunneling, we recently show that Hawking radiations are correlated, and this correlation can carry off all information about the collapsed matter in a black hole. This talk will briefly introduce the relevant background and summarize our work.
