SUMMARY

A single photon cannot exhibit mixed polarization states along a particular axis; this phenomenon is only observable in a beam of multiple photons. The discussion references the Bloch sphere and Poincaré sphere as essential tools for understanding polarization states. Specifically, a photon can be linearly polarized along the x-axis, circularly polarized along the y-axis, but cannot simultaneously possess mixed polarization along the z-axis. This conclusion is supported by established quantum mechanics principles.

PREREQUISITES
  • Quantum mechanics fundamentals
  • Understanding of photon polarization
  • Familiarity with the Bloch sphere
  • Knowledge of the Poincaré sphere
NEXT STEPS
  • Study the Bloch sphere representation of quantum states
  • Explore the Poincaré sphere and its applications in polarization optics
  • Research the implications of photon polarization in quantum communication
  • Investigate the differences between classical and quantum descriptions of light
USEFUL FOR

Physicists, optical engineers, and students of quantum mechanics seeking to deepen their understanding of photon behavior and polarization phenomena.

can a single photon have different kinds of polarization?

say linearly polarized along x-axis
circular polarized along y-axis
mixed polarized along z-axis

actually mixed polarization in a single photon (along a particular axis) cannot happen, right?

it can only happen in a beam (which consists of many photons)
