Abstract

`Interaction-free' measurements (IFM) of the presence of an object with no photons being adsorbed are feasible with an efficiency of >85% by using an application of the quantum zeno effect. For photons that leave on the desired cycle (N = 6), the polarization is found to be horizontal in the absence of an object, and vertical with the object present. Polarimeter cavity is used to demonstrate high-efficiency interaction-free measurements and the Mach-Zehnder polarimeter is used to obtain interaction-free images.
