霍洛维茨和马尔达塞纳提出，如果在黑洞内部的类空奇点上施加一个终态边界条件，则黑洞S矩阵的正则性可以与霍金的半经典论点相一致。我们指出，在这种情况下，由于坍塌的物体和事件视界内流入的霍金辐射之间的相互作用，可能会出现偏离统一性的情况。黑洞蒸发时丢失的信息量取决于这些相互作用纠缠的程度。
Horowitz and Maldacena have suggested that the unitarity of the black hole S-matrix can be reconciled with Hawking's semiclassical arguments if a final-state boundary condition is imposed at the spacelike singularity inside the black hole. We point out that, in this scenario, departures from unitarity can arise due to interactions between the collapsing body and the infalling Hawking radiation inside the event horizon. The amount of information lost when a black hole evaporates depends on the extent to which these interactions are entangling.
