Triphasic Entropy of Time (TET): Entropic Conditioning of State Accessibility in Open Quantum Systems

This preprint introduces the Triphasic Entropy of Time (TET), a phenomenological and effective framework that treats entropy as the primary physical quantity underlying what we perceive as time. TET organizes entropy into three regimes (past as fixed entropy, present as changing entropy, future as pre-conditioned entropy) and proposes a minimal toy model that weights transition probabilities by an effective entropic cost, consistent with Lindblad dynamics. The framework predicts that the informational entropy of the environment may induce measurable biases in decoherence rates and outcome probabilities beyond standard predictions. Experimental proposals using superconducting qubits are discussed to test this idea. This work is presented as an initial phenomenological exploration and is intended to stimulate further theoretical and experimental investigation.
