Abstract

The effect of interaction-free measurements (IFM) on quantum coherence was investigated. The quantum system was subject to measurement dependent decoherences as energy exchanges were insufficient. The design of interaction-free measurement schemes to preserve the state was found feasible. The requirement of quantum coherence preservation yielded very low efficiency. The impact of quantum superposition on the IFM measurements was also presented.
