👉 Heptasemic is a concept in quantum information theory that refers to a phenomenon where a quantum system can exist in multiple states simultaneously, each of which are characterized by different properties. In other words, it describes a state with more than two components (quantum variables) and their interactions. The term "heptasemic" was first introduced by physicist Yves Cattani in 1982, who proposed this concept to describe the quantum states that can exist simultaneously within a single
