Abstract
A Lorentz-symmetry test with Ca+ ions demonstrated the potential of using quantum information inspired technology for tests of fundamental physics. A systematic study of atomic-system sensitivities to Lorentz violation identified the ytterbium ion as an ideal system with high sensitivity as well as excellent experimental controllability. A test of Lorentz-violating physics in the electron-photon sector with Yb+ ions has the potential to reach levels of 10 (-23), five orders of magnitude more sensitive than the current best bounds. Similar sensitivities may be also reached with highly charged ions.
