单原子脉泽:不可分离的原子对

One-atom maser: Non-separable atom pairs

Berthold-Georg Englert, Pavel Lougovski, Enrique Solano, Herbert Walther

摘要:

当一个单原子微波激射器以标准的方式运行时--激发的、共振的二能级原子在随机的时间穿过谐振器--出现的原子与腔场纠缠。因此,对不同原子的测量结果往往是相关的。通过研究这种原子对的约化态的性质,我们发现两个连续原子之间存在真正的非经典关联。特别是,我们计算其程度的可分性,并找到参数范围内,它是显着小于团结。

英文摘要:

When a one-atom maser is operated in the standard way -- excited, resonant two-level atoms traverse the resonator at random times -- the emerging atoms are entangled with the cavity field. As a consequence, the results of measurements on different atoms tend to be correlated. We show that truly non-classical correlations can be found between two successive atoms by studying the properties of the reduced state of such an atom pair. In particular, we calculate its degree of separability and find parameter ranges in which it is markedly less than unity.
