Quantum is deemed to be a distinct container with energy kept in, whereas photon is considered as an elementary particle. Photon and quantum are two very significant principles talked about in modern physics. These principles are broadly used in quantum chemistry, quantum physics, electromagnetic theory, particle physics, optics, etc. These principles are also applied in a lot of actual world applications such as high resolution microscopy, LASERs, measurements of molecular distances, photochemistry, and quantum cryptography. It is highly important to have knowledge and a good understanding in photon and quantum so that we could excel in the aforesaid fields. A photon is an elementary particle, however, a quantum is not an elementary particle. A quantum does not have the properties of both wave like and particle like, but a photon does. A photon is not about a measure of quantity and can be defined as a quantum of energy, on the contrary, a quantum can be described as a measure of quantity.
