Quantum it describes a fundamental aspect of energy not just restricted to photons. In the attempt to bring theory into agreement with experiment, Max Planck postulated that electromagnetic energy is absorbed or emitted in discrete packets, or quanta. Quantum In physics, a quantum (plural: quanta) is the minimum amount of any physical entity (physical property) involved in an interaction. The fundamental notion that a physical property may be "quantized" is referred to as "the hypothesis of quantization". This means that the magnitude of the physical property can take on only discrete values consisting of integer multiples of one quantum. For example,
Interaction information Interaction information The interaction information (McGill 1954), or amounts of information (Hu Kuo Ting, 1962) or co-information (Bell 2003) or information interaction (Licina 2017) is one of several generalizations of the mutual information. In fact, the definition of interaction information is identical to that of multivariate mutual information except for a change in sign in the case of an odd number of random variables except in the work of Licina where information is more like a physical entitiy. Interaction information expresses the amount information (redundancy or synergy) bound up in a set of variables, "beyond" that which is present in
