本项目研究量子信息中若干基础课题及其应用: 量子关联，量子测量与退相干，开放量子系统与量子非马氏性(non-Markovianity)。具体来说，将探讨经典关联与量子关联的刻画与量化，寻找易于计算又有重要物理含义的关联度量，从关联的角度研究量子测量和退相干的信息特征，研究开放系统的信息转移规律，利用关联量化物理演化过程的非马氏性并探讨其对控制开放系统的作用。

This proposal will be devoted to the study of the following fundamental issues and their applications in quantum information: Quantum correlations, quantum measurements and quantum decoherence, quantum open systems and quantum non-Markovianity. More precisely, we will study the characterizartion and quantification of both classical and quantum correlations, introduce physically significant and mathematically computable measures for correlations, explore the informational aspects of quantum measurements and quantum decoherence, investigate the nature of information transfer and flow in quantum open systems, quantify non-Markovianity via correlations and illustrate its application in controlling open systems.
