标题： Time-symmetric quantization in spacetimes with event horizons

摘要： 在具有事件视界的时空中的标准量化形式表明，量子态的演化是非幺正的，因为初始纯态可能会演化为热态。 这一现象导致了著名的黑洞信息丢失悖论，引发了关于量子力学与引力相容性的长期争论。 在本文中，我们证明在另一种时间对称的量化形式中，热辐射是不存在的，并且在具有事件视界的时空中态会幺正演化。 我们还讨论了所提出形式的理论一致性。 我们明确证明该理论保持了微观因果性条件，并提出了一个“重新解释假设”以解决与负能态相关的其他明显病态问题。 因此，由于存在一致的替代方案，我们认为选择使用时间不对称的量化是黑洞信息丢失悖论的必要条件。 显示英文摘要

摘要： The standard quantization formalism in spacetimes with event horizons implies a non-unitary evolution of quantum states, as initial pure states may evolve into thermal states. This phenomenon is behind the famous black hole information loss paradox which provoked long-standing debates on the compatibility of quantum mechanics and gravity. In this paper we demonstrate that within an alternative time-symmetric quantization formalism thermal radiation is absent and states evolve unitarily in spacetimes with event horizons. We also discuss the theoretical consistency of the proposed formalism. We explicitly demonstrate that the theory preserves the microcausality condition and suggest a "reinterpretation postulate" to resolve other apparent pathologies associated with negative energy states. Accordingly as there is a consistent alternative, we argue that choosing to use time-asymmetric quantization is a necessary condition for the black hole information loss paradox.
