报告摘要：
美猴王孙悟空具有很多降妖覆魔的法力。其中重要的一个是他的分身术，即他能在同一时间幻身在不同的地方以迷惑敌人。在这儿我将讨论孙悟空如何利用量子力学来实现这一法力。在我们的实验中，我们将一个来回振荡的物体比如摆动的琴弦的能量降到绝对零度附近，生成所谓的量子机。这个量子机的特点是它可以在同一时间处在两个或多个不同的量子态，或者等效地说它可以在同一时间出现在两个或多个不同的地方。我会具体描述物理学家是如何做到这一点的。当然，看起来孙悟空还需要超越量子力学的能力来实现他的全部法力。

Sun Wukong, the Chinese monkey king, is attributed with magical powers that enable him to defeat his enemies. One magical power might be the ability to be in two places at one time. Here I will explore the way Sun Wukong might employ quantum mechanics to achieve this feat. In our physics experiments, we have created a special experiment in which a mechanical device can be prepared in two quantum states at one time, the equivalent of being in two places at the same time. I will describe what the physicist needs to do to make this happen; unfortunately, it appears that Sun Wukong must have powers beyond those given by quantum mechanics to perform his tricks.
Dr. ANDREW N. CLELAND is a professor of physics at the University of California at Santa Barbara, a position he has held since 1997. He is an expert in quantum integrated circuits, nanomechanics and microfluidics. He has published over 100 refereed journal articles and has given over 100 public presentations of his scientific work, both in the U.S. and internationally. He is author of a textbook (Foundations of Nanomechanics, in English and Chinese) and is named as inventor on two patents. He has been elected a Fellow of the American Physical Society and a Fellow of the American Association for the Advancement of Science. Recent work from his research group was selected as the Breakthrough of the Year by Science magazine (2010), and has been featured in newspapers around the world. He holds a PhD in physics and a BS in engineering, both from the University of California at Berkeley.
