Definition

Quantum superposition is the coherent plurality of possible quantum states or alternatives before a determinate outcome, with contributions that can reinforce or cancel in the relevant measurement arrangement. The manuscript uses it to challenge the picture of an already settled classical state merely hidden from view. Its RTI account treats those possibilities as real potentia; that ontological reading is adopted rather than established uniquely by the phenomenon.

Explanation

The introductory cat example is a thought experiment that dramatizes tension between quantum description and definite macroscopic outcomes. Its loose language of a mix must not erase coherence: indistinguishable contributions combine before their outcome weights are formed. The proposal therefore distinguishes superposition from an ordinary list of unknown but already settled alternatives.

The storage discussion supplies a concrete qualification. A delocalized single excitation can be stored and retrieved with interference intact; not every interaction or temporary uptake is thereby an irreversible record. The cited experiment is a benchmark for the proposed absorption criterion, not an experiment that newly proves the adopted transactional ontology.

RB3 locates coherent states within a costly material apparatus of preparation, shielding, correction and measurement. Superposition does not deliver unlimited computational power or free an arrangement from constraints. The entry preserves the source’s realist interpretation while leaving the general quantum phenomenon distinct from its philosophical extension to becoming at other scales.
