Antiphotons

Antiphotons are hypothetical antiparticles of photons. Photons are the fundamental particles of light and electromagnetic radiation, and they are their own antiparticles, meaning a photon is identical to its antiparticle. This is a unique property among fundamental particles. While most other particles, such as electrons, have distinct antiparticles (positrons), the photon's self-conjugate nature means there is no separate entity referred to as an antiphoton. When a photon is created, it is simply a photon. Similarly, when an antiparticle is needed for a process involving electromagnetic interaction, it is still described in terms of photons. The concept of an antiphoton is therefore not a distinct physical entity but rather a theoretical consideration that, in practice, leads back to the properties of the photon itself. The interaction of matter and antimatter involves the annihilation of both, producing photons. For instance, an electron and a positron annihilate to form two or more photons. However, the photons produced are indistinguishable from any other photons.
