利用正交直积态的量子密钥分配协议

基于量子密钥分配协议是目前实现密钥分配最安全的方法,两个三态量子位组成的复合系统中存在一组正交直积态,它可以表现出非定域性。该文提出了一个建立在该系统的非定域性基础上的量子密钥分配协议,协议双方通过交换量子位和集体测量建立起共享的密钥。量子力学的基本原理保证了该协议是无条件安全的,没有第三方可以窃取密钥而不被发现。该协议不需要纠缠态,也不需要做任何量子操作。因此,它更容易在实践中实现,同时具有更高的可靠性与健壮性。     

论玻姆的量子势因果解释及非定域性观点

本文评介了玻姆的量子势因果解释及非定域性观点.量子势解释作为玻姆的量子理论因果解释的核心在八十年代以后受到玻姆的真正重视.玻姆从信息的角度重新看待量子势,提出了若干新的观点.尤其是,玻姆从量子势、活动信息出发对非定域性问题进行了新的探索.这在物理学上和哲学上都有重要意义.     

The Dynamics of Self-Organization

ABSTRACT

The following reviews the promises and limitations for social work of self-organization theory, an integral part of the emerging field of complex systems. Self-organization refers to the capacity of many systems to spontaneously develop novel forms of organization with little external interference. The primary focus of the review involves what the author contends are several neglected dimensions of higher level self-organizing systems, specifically: (1) the role of consciousness and intentionality; (2) the capacity for self-selection as a means of seeding self-organizing processes; and (3) the possibility that some forms of self-organization are based on nonlocal processes involving the synchronistic correlation between separated parts of systems.
