| contents | <p>The Born rule assigns probabilities to measurement outcomes under the assumption that a quantum system retains a well-defined identity within a stable coarse-grained description. Experimental studies of open quantum systems, error correction, monitored dynamics, and decoherence report abrupt “avalanche”-like transitions in which probabilistic descriptions of subsystems rapidly fail, even though global unitary evolution is preserved.</p> <p>This work provides a structural interpretation of such transitions by identifying an identity tolerance boundary, denoted Ω, beyond which the thermodynamic identity of a quantum system ceases to be well defined. When cumulative irreversible entanglement or decoherence exceeds this boundary, Born-rule probabilities no longer apply—not due to a failure of quantum mechanics, but because the probabilistic description presupposes a persisting system identity that has been lost.</p> <p>The framework does not introduce new physical laws, collapse mechanisms, or modifications to quantum theory. Rather, it clarifies the domain of applicability of probabilistic descriptions by explicitly separating fine-grained unitary evolution from the persistence of macroscopic or subsystem identity. This perspective unifies observations across decoherence avalanches, error-correction thresholds, and measurement-induced transitions without proposing operational procedures or control mechanisms.</p> |
