摘要:

物理学家普遍认为,量子系统的纠缠态很快就会失去它们的相干性。原因在于,任何与环境的相互作用都会使量子态坍缩,而这种相互作用会区分纠缠的子系统。在这里,我们研究纠缠态的两个捕获的钙$^+$离子和观察强大的纠缠持续超过20秒。

英文摘要:

It is common belief among physicists that entangled states of quantum systems loose their coherence rather quickly. The reason is that any interaction with the environment which distinguishes between the entangled sub-systems collapses the quantum state. Here we investigate entangled states of two trapped Ca$^+$ ions and observe robust entanglement lasting for more than 20 seconds.
