SUMMARY

Photons carry information through their quantum states, similar to how emails or telegrams convey messages. Each photon can exist in various quantum states, which can be represented by symbols such as letters or numbers. The ability to distinguish between these states directly impacts the efficiency of encoding and decoding information. This understanding is crucial for advancements in quantum communication technologies.

Ok, so I don't understand, what information is a photon carrying? It's mass, velocity or something like that?

The information a photon carries is just like the information an email or telegram carries.

There are many different possible quantum states a photon or group of photons can be in.

If we assign a letter, number or other symbol to each possible quantum state, we can send that photon in some quantum state from A to B, where it can be received, and read.

The better we care able to distinguish between different states of a photon, the better we are able to write and read information encoded in photon states.
