中文摘要: 量子信息和量子计算是基于量子力学理论的具有重要应用性的一门前沿学科,量子关联是量子信息和量子计算能优于经典通信和经典计算的根本原因。量子关联度量方式的提出和物理体系中量子关联变化的研究在量子信息和量子计算的学科中占有重要地位。本项目在已有工作基础上,针对这些热点问题,拟开展以下探索:1. 给出高维空间中高维多体量子态的量子失协的度量方法,并讨论高维多体量子态关联程度与量子失协的关系;2. 完善高维空间中量子态的量子局域不确定度的理论;3. 量子关联在量子随机行走物理系统中的应用,研究量子随机行走中量子失协和量子局域不确定度的变化以及与随机行走中重要物理特点的关系。

英文摘要: Quantum calculation and quantum information is a frontier discipline based on quantum mechanic that has important applicabilities. It is the source of quantum information and calculation is superior to classical information and calculation. The proposition and the application of quantum correlation measurement play a key role in quantum information and communication. Based on the previous work, we project to come to the following fruitful results: 1 we expect to give the quantum discord measurement in high dimensional multipartite quantum state, and research the relation of quantum discord and quantum correlation degree. 2 complete the local quantum uncertainty theory in high dimensional quantum state. 3 investigate the quantum correlation effects on some important phenomenon in quantum random walk system.
