理论上，根据复合噪声环境下的解缠行为，两量子比特系统的希尔伯特空间可以分为两个独立的部分：一个三维子空间，在这个空间中，所有的态都渐近解缠，其余的所有态突然解缠。弱噪声物理下纠缠衰减率对加性的破坏。莱特牧师。
Received 27 October 2008; published 29 January 2009We theoretically show that according to the disentanglement behavior under a composite noise environment,the Hilbert space of a two-qubit system can be divided into two separate parts: a three-dimensional subspacein which all states disentangle asymptotically, and the rest in which all states disentangle abruptly.
