AI总结:

本文提出一种基于多离子纠缠态的协议,在钡离子中实现低于0.1%精度的原子宇称破坏测量,通过共模抑制和选择性探测,免除了11个数量级的系统误差抑制,并可扩展至大规模离子数以提高精度。

摘要:

本文提出了一种以低于0.1%的精度测量钡离子中原子宇称破坏(APV)的方案。该方案基于使用多离子纠缠态来共模抑制宇称守恒的系统性位移,并选择性地探测宇称破坏的矢量光位移。该测量协议消除了将主要系统性误差抑制11个数量级的需要,而这在单离子测量方案[N. Fortson, Phys. Rev. Lett. 70, 2383 (1993)]中是必需的。此外,该协议可以与集成光子波导结合使用,采用一种可扩展至大量离子数的架构,测量精度随离子数成比例提高。

英文摘要:

This paper proposes a scheme to measure atomic parity violation (APV) in barium ions at <0.1% precision. The scheme is based on using multi-ion entangled states to common-mode reject parity-conserving systematic shifts and selectively detect a parity-violating vector light shift. This measurement protocol eliminates the need to suppress a leading systematic by 11 orders of magnitude, as is required in the single-ion measurement scheme [N. Fortson, Phys. Rev. Lett. 70, 2383 (1993)]. Furthermore, the protocol can be combined with the use of integrated photonic waveguides in an architecture that is scalable to large ion numbers, with a proportional increase in measurement precision.
