- 摘要:
- 在光纤连接的低品质腔中利用法拉第旋转机制提出了一个制备四原子团簇态的方案.在方案中,4个原子分别被囚禁在用光纤连接的4个低品质耦合腔中,并且信息编码在4个三能级原子的基态上,因此方案对腔衰减和原子自发辐射都不敏感,所制备的纠缠态稳定.
- Abstract:
- We propose a scheme for preparing a four-atom cluster state via photonic Faraday rotations in loss optical cavities connected by optical fibers. In this scheme, four three-level atoms are trapped inside coupled cavities, and the information is encoded in the low energy level, therefore our scheme is insensitive to both cavity decay and atomic spontaneous emission, so that the entanglement is more stable.
