小球穿墙而过,诺奖看见“量子革命”
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 ...
