为"普适量子论"的天平再压下有力量的一格。 当小球以单个粒子形态存在时，这一看似不可能的现象成为可能，它就是"量子隧穿"， 是一种量子力 学现象。 量子力学通常用来解释微观世界现象，如单个粒子、原子或电子的行为。当系统变得越来越大，粒子越 来越多时，量子效应就会被各种相互作用破坏掉，变得几乎看不见。 例如，一个由众多分子组成的小球不会表现出量子力学效应，球每次都会撞到墙上反弹，这就是人们熟 悉的宏观世界。 想象一下，有一颗小球，放在被墙分隔为左右两侧的房间里。按常理，它们只能在自己这一侧滚动，除 非有人在墙中开一个洞。但小球忽然无声无息地出现在墙的另一边：没有门、没有钥匙，墙也完好无 损，小球却完成了过墙。 让量子现象肉眼可见 今年获得诺贝尔物理学奖的三位物理学家约翰·克拉克（John Clarke）、米歇尔·德沃雷（Michel H. Devoret）和约翰·马丁尼斯（John M. Martinis）就在实验中证明，量子隧穿并不只属于微观世界，也可 以出现在由无数粒子组成的宏观尺度系统中。即特定条件下，原本只在微观世界中存在的量子现象，在 宏观尺度上展现了出来。 （约翰·克拉克、米歇尔·德沃雷和约翰·马丁 ...
