Description / Abstract This work proposes a process-based interpretation of the quantum switch as an emergent structure arising from discrete, packed quantum processes denoted as P. Instead of treating the quantum switch as a primitive resource associated with an indefinite causal order, we demonstrate that it can be understood as a higher-level process configuration constructed from elementary discrete process units. The proposed framework introduces a pentacle-based quantum language, in which quantum operations are organized as process graphs rather than time-ordered circuits. Within this approach, causal order is not assumed a priori but emerges from the structural relations between discrete processes. The quantum switch appears naturally as a stable process pattern enabled by coherent superposition and entanglement of operational pathways. This perspective aligns with process-matrix formulations and is conceptually consistent with the Everett (many-worlds) interpretation of quantum mechanics, avoiding collapse postulates and treating the wave function as universally valid. The framework suggests experimentally testable implications using interferometric and photonic implementations of the quantum switch and provides a conceptual bridge between quantum information processing, quantum foundations, and discrete models of quantum dynamics.
