The various aspects of the Kochen-Specker (KS) theorem with single photons were presented. A complex formulation, designed by the KS theorem, was used to present the compatibility of noncontextual hidden variables (NCHV) with quantum mechanics. A two-qubit system was formed with the help of polarization and path degrees of single photon.
