摘要
量子力学要求封闭系统必须遵循幺正演化,即封闭系统演化信息守恒。黑洞信息丢失问题与量子力学幺正性产生了冲突,暗示了量子理论可能无法正确地描述引力。文章介绍了黑洞信息丢失问题的来源,以及可能的解决方法。
Unitarity is required by quantum mechanics for the dynamics of any closed systems,i.e.,information is conserved for closed systems.The black hole information loss conflicts to the unitarity,which indicates the impossibility of unifying quantum mechanics with gravity.In this paper,we review the origin of the puzzle and the possible solutions.
