Abstract: An entangled state prepared in a decoherence free sub-space together with aRamsey type measurement can probe parity violation in heavy alkali ions likeBa+ or Ra+. Here we propose an experiment with Ba+ as an example to measure thesmall parity violating effect in this system. It has been shown that ameasurement on a maximally correlated system will reduce the uncertainty ascompared to that on a single ion measurement. In addition it also provides afeasible solution to measure the nuclear spin dependent part of the totalparity violating light shift in an ionic system which has so far not beenaddressed.
