What is the similarity between the concept of quantum and photon?

In summary, a photon is the tiniest possible particle of light, a quantum of light. A quantum, on the other hand, is the tiniest possible particle of any substance at the subatomic level and includes, for example, electrons and neutrinos.

A quantum is a packet of energy of definite magnitude, which may or may not be light energy. A photon is a packet of light energy having a difinite magnitude. Thus, a quantum may not be a phoyon but photon is a quantum.
