论文摘要
我们提出了一种使用相互作用的玻色子凝结物来捕获原子干涉法的方案。冷凝物通过串联的bragg脉冲控制在两个狭窄的外部动量模式下进行控制，并在空间上分裂。所提出的方案（i）允许通过原子间相互作用引起的单轴扭曲动力学在捕获的干扰计配置中产生大纠缠，并且（ii）避免在干涉仪序列过程中通过在相位编码前后对状态进行仔细操纵，从而避免抑制相互作用。干涉仪可用于测量重力，其灵敏度超出标准量子极限。
We propose a scheme for trapped atom interferometry using an interacting Bose-Einstein condensate. The condensate is controlled and spatially split in two confined external momentum modes through a series Bragg pulses. The proposed scheme (i) allows the generation of large entanglement in a trapped-interferometer configuration via one-axis twisting dynamic induced by interatomic interaction, and (ii) avoids the suppression of interactions during the interferometer sequence by a careful manipulation of the state before and after phase encoding. The interferometer can be used for the measurement of gravity with a sensitivity beyond the standard quantum limit.
