退相干与量子轨道

Decoherence and quantum trajectories

Todd A. Brun

摘要:

退相干是量子系统相互作用并与外部环境相关的过程;量子轨迹是一种强大的技术,通过这种技术,可以将退相干系统分解为随机演化,以不同的环境“测量”为条件。通过调用最近开发的量子信息理论工具,我们可以分析退相干的简化模型,明确量化系统、环境和潜在观察者之间的信息流和随机性。

英文摘要:

Decoherence is the process by which quantum systems interact and become correlated with their external environments; quantum trajectories are a powerful technique by which decohering systems can be resolved into stochastic evolutions, conditioned on different possible ``measurements'' of the environment. By calling on recently-developed tools from quantum information theory, we can analyze simplified models of decoherence, explicitly quantifying the flow of information and randomness between the system, the environment, and potential observers.
