Photons – Polarization, Phase and Entanglement

Modelling Photon Phase


Modelling a photon presents a number of challenges. In quantum physics, a photon flies through the air like a wave. They diffract around corners like a wave. Photons interact with each other like waves. Sometimes they reinforce each other, sometimes they interfere and seem to disappear. The classical explanation uses Maxwell’s equations to describe the wave nature of light. Light waves […]

Modelling Quantum Entanglement


The polarization of the photon refers to the “direction” of the axis of the energy field, with the magnetic axis being offset by 90°. Polarization can be a direction like up or down, left or right. Polarization can also mean spin in a clockwise or counter-clockwise direction. The axis of the electric field may be rotating or spinning in time and […]
