摘要

讨论了光量子放大器受激发射复制量子态的信息问题。结果表明，当单光子放大到几个光子的水平时，可测量的信息迅速减少。本文还讨论了导致这种行为的自发辐射。

Copying of quantum information by means of a quantum amplifier

Information aspects of copying quantum states via stimulated emission of an optical quantum amplifier are considered. It is shown that the measurable information very rapidly decreases after amplification of a single photon up to a level of several photons. Spontaneous emission, which leads to such behavior, is also discussed.
