量子涨落与生命

Quantum fluctuations and life

P. C. W. Davies

摘要:

有许多人声称,量子力学在生物有机体的起源和/或运作中起着关键作用,而不仅仅是为生物分子的形状和大小及其化学亲和力提供基础。从薛定谔提出的量子涨落会产生突变,到哈默洛夫和彭罗斯提出的微管中的量子相干性与意识有关的猜想。我在本文中回顾了其中的一些主张,并讨论了退相干的严重问题。对生物系统中的量子信息处理作了进一步的探讨。提出了一些可能的实验。

英文摘要:

There have been many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms, beyond merely providing the basis for the shapes and sizes of biological molecules and their chemical affinities. These range from the suggestion by Schrodinger that quantum fluctuations produce mutations, to the conjecture by Hameroff and Penrose that quantum coherence in microtubules is linked to consciousness. I review some of these claims in this paper, and discuss the serious problem of decoherence. I advance some further conjectures about quantum information processing in bio-systems. Some possible experiments are suggested.
