如果时间是一个局部可观测量,那么霍金辐射是么正的

If time is a local observable, then Hawking radiation is unitary

H. Nikolic

摘要:

在量子理论的通常表述中,时间是一个整体的经典演化参数,而不是一个局部的量子可观测量。另一方面,正则量子引力(它缺乏基本的时间演化参数)和时空协变性原理(它坚持时间应该与空间平等对待)都表明,量子理论应该稍微重新表述,以一种将时间提升为局部可观测的方式。这样一个重新表述的量子理论比通常的量子理论在更一般的意义上是幺正的。特别地,这将非幺正的霍金辐射提升为幺正现象,从而避免了黑洞信息悖论。

英文摘要:

In the usual formulation of quantum theory, time is a global classical evolution parameter, not a local quantum observable. On the other hand, both canonical quantum gravity (which lacks fundamental time-evolution parameter) and the principle of spacetime covariance (which insists that time should be treated on an equal footing with space) suggest that quantum theory should be slightly reformulated, in a manner that promotes time to a local observable. Such a reformulated quantum theory is unitary in a more general sense than the usual quantum theory. In particular, this promotes the non-unitary Hawking radiation to a unitary phenomenon, which avoids the black-hole information paradox.
