The quantum marking and quantum eraser for neutron kaons were discussed. It was found that the neutral kaon system was suitable to discuss extensions and tests of Bohr's complementarity principle through the quantum marking and quantum erasure technique. The strangeness oscillations played the role of the traditional interference pattern linked to wavelike behavior. Analysis show that the quantum erasure allows one to restore the same KS-KLinterference phenomenon exhibited by a single kaon state produced as K0or K̄0.
