Photon polarization is the quantum mechanical description of the classical polarized sinusoidal plane electromagnetic wave. An individual photoncan be described as having right or left circular polarization, or a superposition of the two. Equivalently, a photon can be described as having horizontal or vertical linear polarization, or a superposition of the two. Many of the implications of the mathematical machinery are easily verified experimentally. In fact, many of the experiments can be performed with polaroid sunglass lenses.
