论文摘要
与环境相互作用的量子系统可以将系统信息的冗余编码诱导到多部分环境中，这是量子达尔文主义的本质。同时，环境可能会扰乱有关系统的最初本地化信息。我们主要研究了在环境中争夺的信息与量子达尔文主义的出现之间的相关性。首先，我们通常会确定，当系统显示最初位于环境中的达尔文行为系统信息时，当达尔文主义消失时发生时，我们会遇到我们的结果。然后，我们通过一个或两个Qubits组成的系统通过一个或两个Qubits互动的系统来验证我们的结果。系统对于QD的出现和争夺的系统行为有所不同，但是它们之间的上述相关性仍然有效。
Quantum system interacting with environment can induce redundant encoding of the information of system into a multipartite environment, which is the essence of quantum Darwinism. At the same time, environment may scramble the initially localized information about the system. We mainly investigate the relevance between information scrambling in environment and the emergence of quantum Darwinism. First, we generally identify that when the system shows a Darwinistic behavior system information that is initially localized in the environment is not scrambled, while when Darwinism disappears scrambling occurs.We then verify our result through a collision model where the system, consisting of one or two qubits, interacts with an ensemble of environmental ancillas.Moreover, dependent on the nature of system-environment interactions, our results also shows that the single qubit and two-qubit systems behave differently for the emergence of QD and the scrambling, but the above relevance between them remains valid.
