【摘要】 提出了一个由两光纤连接的三个分离腔中远程制备三原子W态的方案。制备过程中,由于原子系统、腔模和光纤模均处于非激发态,该方案能有效地抑制原子的自发辐射、腔衰减以及光纤泄露。相比于其他方案,此方案的优点是所用的绝热演化方法对实验参数的变化不敏感。另外,该方案可以简单推广到制备n个原子的W态。更多还原

【Abstract】 A scheme was proposed for implementing the entangled W state of three atoms trapped in distant cavities connected by single-mode fibers.The scheme is robust to atomic spontaneous decay,cavity decay and photon leaking out of the fiber due to that the atomic system,all the modes of cavity fields and fibers are only virtually excited.Compared to the previous schemes, the significant advantage is that the adiabatic passage is applied in the scheme.It does not need precise control of the Rabi frequency,pulse duration and is insensitive to moderate fluctuations of experimental parameters.In principle,the n-atom W state can be prepared by using such a method.更多还原
