Division of the two-qubit Hilbert space according to the entanglement sudden death under composite noise environment
arXiv:0808.1934 · doi:10.1103/PhysRevA.79.014303
Abstract
We show theoretically that according to the disentanglement behavior under composite noise environment, the Hilbert space of a two-qubit system can be divided into two separate parts: a 3-dimensional subspace in which all states disentangle asymptotically, and the rest in which all states disentangle abruptly. The violation of additivity for entanglement decay rates under weak noises [see, PRL 97, 140403 (2006)] therefore can be explained in terms of such division of the Hilbert space.
