量子物种的复制与进化
Replication and Evolution of Quantum Species
摘要:
从薛定谔和维格纳开始,我们详细讨论了物理学家关于“生命”的概念,一直到量子信息下的生命系统的现代语言。我们从量子生物信息的角度讨论了生命系统的一些基本特征,如普通的复制和进化。我们还讨论了活副本的无淘汰原则。我们表明,在一个相同物种的集合中,在一个封闭的宇宙中,突变的副本之一和物种的其余部分之间不可能有纠缠。尽管这些讨论围绕着“人工生命”展开,但在适当的条件下,它们仍可能适用于真实的生物系统。
英文摘要:
We dwell upon the physicist's conception of `life' since Schroedinger and Wigner through to the modern-day language of living systems in the light of quantum information. We discuss some basic features of a living system such as ordinary replication and evolution in terms of quantum bio-information. We also discuss the principle of no-culling of living replicas. We show that in a collection of identical species there can be no entanglement between one of the mutated copies and the rest of the species in a closed universe. Even though these discussions revolve around `artificial life' they may still be applicable in real biological systems under suitable conditions.
