这个那天在 Discovery Channel 看到~ 但是他解说的那个 two atoms 的地方俺很不明白~ 他说如果其中一个 atoms 发消息给另一个 atom 后~ 两个 atoms 就会同步(synchronize)~ 后就会有着同样的东西会发生~ 那么这是 teleport 还是复制离子结果？

量子世界有两大神秘性质：

1. 海森堡不确定性原理 Heisenberg's uncertainty principle，一个粒子的位置和它的动量不可被同时确定，the double-slit experiment is a manifestation of Werner Heisenberg's uncertainty principle，which states that it is not possible to precisely measure both the position (which of the two slits has been traversed) and the momentum (represented by the interference pattern) of a photon。

2. 量子纠缠 quantum entanglement，两个相距较远的粒子会彼此互相影响，爱因斯坦称之为“远距离的幽灵般作用 spooky action-at-a-distance”，纠缠也被称为非局域性 quantum non-locality。

后来也有了Quantum teleportation 量子遥传

Quantum teleportation is unrelated to the common term teleportation - it does not transport the system itself, and does not concern rearranging particles to copy the form of an object

量子遥传（Quantum teleportation），又称量子隐形传输或量子隐形传送或量子隐形传态或量子远距传输或量子远传，是一种利用分散量子缠结与一些物理讯息（Physical information）的转换来传送量子态（Quantum state）至任意距离的位置的技术。量子遥传并不会传送任何物质或能量。

A quantum machine is a human-made device whose collective motion follows the laws of quantum mechanics. The idea that macroscopic objects may follow the laws of quantum mechanics dates back to the advent of quantum mechanics in the early 20th century. However, as highlighted by the Schrödinger's cat thought experiment, quantum effects are not readily observable in large-scale objects. Consequently, quantum states of motion have only been observed in special circumstances at extremely low temperatures. The fragility of quantum effects in macroscopic objects may arise from rapid quantum decoherence, although currently there is insufficient evidence to support this claim. Researchers created the first quantum machine in 2009, and the achievement was named the "Breakthrough of the Year" by Science in 2010...
