我们提出了一个有效的方案，工程多原子纠缠通过检测腔衰减通过单光子探测器。在两个原子的特殊情况下，该方案比以前的概率方案更有效，并且对原子位置的随机性不敏感。更一般地说，该方案可用于制备多原子迪凯态的任意叠加态，而不需要对不同原子进行高效率的探测和单独寻址。
We propose an efficient scheme to engineer multiatom entanglement by detecting cavity decay through single-photon detectors. In the special case of two atoms, this scheme is much more efficient than previous probabilistic schemes, and insensitive to randomness in the atom's position. More generally, the scheme can be used to prepare arbitrary superpositions of multiatom Dicke states without the requirements of high-efficiency detection and separate addressing of different atoms.
