What Is the Single-Outcome Problem in Quantum Mechanics?
The single-outcome problem concerns how definite individual measurement records relate to a formalism that represents multiple possible quantum outcomes.
Fix the object first.
The problem is narrower than the entire measurement problem. It focuses on the relationship between a state containing multiple outcome-associated components and the fact that an observer or apparatus records a definite result in an individual run.
The visible label is not the whole system.
Keeping this burden separate prevents three different questions from being collapsed into one: what outcomes are possible, how they are weighted, and what account is given of the definite result.
Trace the burden.
- Definite records are part of ordinary experimental practice.
- Foundational approaches explain or redescribe those records in different ways.
- Whether the single-outcome question requires a new physical law is interpretation-dependent.
- Empirical discrimination among interpretations remains difficult in many cases.
Where the work adds something.
CBR accepts the burden as a candidate physical target and attempts to formulate a non-circular realization law. The page explicitly does not claim that all interpretations must accept that target.
