在量子粒子相互作用后，它们通常保持纠缠态，并通过量子力学链接在一段距离内相互关联，量子力学链接可用于以非经典方式传输和处理信息。这意味着可编程的操作序列，以生成和分析复杂系统的纠缠。我们已经为两个原子和一个单光子腔模式演示了这样的过程，通过一系列分别处理粒子的受控步骤来设计和分析三粒子纠缠态。这种纠缠过程原则上可以对更多的粒子进行操作，为量子理论的基本测试打开了新的视角。
After quantum particles have interacted, they generally remain in an entangled state and are correlated at a distance by quantum-mechanical links that can be used to transmit and process information in nonclassical ways. This implies programmable sequences of operations to generate and analyze the entanglement of complex systems. We have demonstrated such a procedure for two atoms and a single-photon cavity mode, engineering and analyzing a three-particle entangled state by a succession of controlled steps that address the particles individually. This entangling procedure can, in principle, operate on larger numbers of particles, opening new perspectives for fundamental tests of quantum theory.
