四原子量子比特纠缠态的产生

Production of genuine entangled states of four atomic qubits

Gui-Yun Liu, Le-Man Kuang

摘要:

我们提出了一个利用单光子源、分束器和单光子探测器在光学腔中产生四个原子量子比特的真正纠缠态的方案。我们展示了如何确定性地产生四个原子量子比特的16个正交归一化和独立的真正纠缠态。发现这16个纠缠态构成了四原子量子比特系统的一种新的表示形式,真正的纠缠态表征这种表示为更好地理解多体纠缠带来了新的有趣的见解。

英文摘要:

We propose an optical scheme to generate genuine entangled states of four atomic qubits in optical cavities using a single-photon source, beam splitters and single photon detectors. We show how to generate deterministically sixteen orthonormal and independent genuine entangled states of four atomic qubits. It is found that the sixteen genuine entangled states form a new type of representation of the four-atomic-qubit system, i.e., the genuine entangled-state representation. This representation brings new interesting insight onto better understanding multipartite entanglement.
