引力退相干的经典信道模型

A classical channel model for gravitational decoherence

D. Kafri, J. M. Taylor, G. J. Milburn

摘要:

我们表明,通过处理两个机械谐振器之间的引力相互作用作为一个经典的测量通道,引力退相干模型的结果是等效的模型首先提出的Diosi。由此产生的退相干模型意味着两个引力耦合谐振器之间的经典介导的引力相互作用不能产生纠缠。引力退相干率(和互补加热率)的数量级的引力诱导的两个谐振器的正常模式分裂。

英文摘要:

We show that, by treating the gravitational interaction between two mechanical resonators as a classical measurement channel, a gravitational decoherence model results that is equivalent to a model first proposed by Diosi. The resulting decoherence model implies that the classically mediated gravitational interaction between two gravitationally coupled resonators cannot create entanglement. The gravitational decoherence rate ( and the complementary heating rate) is of the order of the gravitationally induced normal mode splitting of the two resonators.
