- 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.
