When unpaired electron spins line up parallel to each other, you get ferromagnetism, or a mineral that's an actual magnet.

当未配对的电子自旋互相平行时，你将见到铁磁性，或者一个实际上是磁体的矿物。

Qubits are special because they’re based on the physical properties of particles, like an electron’s spin.

量子比特之所以特殊，是因为它们基于粒子的物理特性，例如电子的自旋。

Electron spin is a superposition of spin up or spin down so we can label spin up zero and spin down one.

电子自旋是向上自旋或向下自旋的叠加， 因此我们可以将向上自旋标记为零， 向下自旋标记为 1。

And then they double-checked by doing some more radioactive uranium and electron spin resonance dating on a fossilized tooth, which gave an estimate of 286,000 years.

然后，他们通过对一颗牙齿化石进行一些更具放射性的铀和电子自旋共振测年来进行复核，估计其存在时间为 286,000 年。

She takes the electrons in a phosphorus atom encased in a silicon crystal, and she's able to manipulate the way these electrons spin, putting them into superpositions and entangling them together.

她将电子包裹在硅晶体中的磷原子中，她能够操纵这些电子的旋转方式，将它们置于叠加状态并将它们纠缠在一起。
