摘要

Recently,the Kochen-Specker theorem has been demonstrated and quantum contextuality has been observed experimentally by using special and independent quantum states.On the other hand,recent investigations have shown that a thermal light source can mimic the two-photon entangled source to perform the imaging effects.We perform an all-or-nothing-type Kochen-Specker experiment using the thermal light source and obtain the same results as those using quantum sources.The physical origin for such a phenomenon is analyzed.
