Search for Lorentz symmetry violation with entangled Yb$^+$ ions

ORAL

Abstract

Recent breakthrough in application of quantum information techniques for test of fundamental physics [T. Pruttivarasin et al., Nature, v.517, 592 (2015)] opened a pathway toward improved probes of Lorentz symmetry violation in electron-photon sector. Here, we describe a detailed scheme based on Yb$^+$ entangled ions that we find to be the best system for such tests that can be carried out with already existing technologies. We estimate the factor of $2.5\times 10^4$ improvement in Lorentz-violation limits with the new scheme.
