Superposition Without Position: Admissibility, Records, and the Binary Structure of Physical Outcomes
Abstract
Quantum superposition is often informally interpreted as the simultaneous realization of mutually incompatible outcomes. This paper argues that such readings conflate predictive structure with recordable states. We clarify the operational role of superposition in recordsupporting physics by distinguishing between the quantum state as a pre-commitment structure and outcomes as committed record states. The central thesis is that wherever stable records exist—states that can be copied, compared, and embedded in memory chains—outcomes are necessarily exclusive within the relevant measurement context. Superposition does not introduce a third ontic position beyond the alternatives; rather, it encodes interference-capable structure over alternatives prior to commitment. The argument is interpretation-neutral. It is compatible with collapse theories, decoherenceonly approaches, and Everettian formulations, where binary commitment is enforced locally within each record-bearing branch. We show that branching multiplies exclusive commitments rather than relaxing them, since the universal wavefunction itself is not a record. Building on this, the paper analyzes the admissibility constraints imposed by record formation, the role of decoherence as a dynamical filter, and the necessity of identity and countability for empirical comparability. Finally, we distinguish imagination, which can entertain contradictions, from physical recordability, which cannot. The result is a conservative structural account of why “superposition” can mislead when read as “position,” and why exclusivity is unavoidable at the level of outcomes.
