自由振荡原子干涉仪中粒子间相互作用的影响

Effect of inter-particle interaction in a free oscillation atomic interferometer

Thomás Fogarty, Anthony Kiely, Steve Campbell, Thomas Busch

摘要:

研究了自由振荡原子干涉仪中两个相互作用玻色子在分束器上的多次散射动力学。使用粒子间散射长度和分束器概率作为控制参数,我们表明,即使在这样一个简单的设置可以创建一个广泛的强关联量子态。这特别包括NOON状态,其最大化量子费舍尔信息并且是量子精密测量中的最重要的状态。

英文摘要:

We investigate the dynamics of two interacting bosons repeatedly scattering off a beam-splitter in a free oscillation atom interferometer. Using the inter-particle scattering length and the beam splitter probabilites as our control parameters, we show that even in a simple setup like this a wide range of strongly correlated quantum states can be created. This in particular includes the NOON state, which maximizes the quantum Fisher information and is a foremost state in quantum metrology.
