πŸ”—
A more photon-specific version of the Bloch sphere.
πŸ”—
In it, each of the six sides has a clear and simple to understand photon polarization state, either of:
  • left/right
  • diagonal up/diagonal down
  • rotation clockwise/counterclockwise
πŸ”—
The sphere clearly suggests for example that a rotational or diagonal polarizations are the combination of left/right with the correct phase. This is clearly explained at: Video 38. ""Quantum Mechanics 9b - Photon Spin and Schrodinger's Cat II" by ViaScience (2013-11-11)".
