Resolution of the problem of definite outcomes

Art Hobson

This paper resolves the problem of definite outcomes, also known as "Schrodinger's cat" and the "problem of wavefunction collapse." It's the problem of understanding how nature goes from a coherent superposition of possible outcomes to a single definite outcome. This "measurement problem" has not to my knowledge been solved. The analysis stems from an insight into entanglement demonstrated in two nonlocality experiments involving pairs of momentum-entangled photons. These show that an entangled state of two subsystems is not a superposition of products of paired states, but instead a superposition of correlations between paired states. The "premeasurement state" is just such a superposition with the proviso that one subsystem is the detector of the other subsystem. This state is not a paradoxical superposition of macroscopic detector states; it is instead a superposition of correlations between detector states and microscopic quantum states. Thus, Schrodinger's cat isn't "smeared" between dead and alive but instead represents a nonlocal superposition of correlations between states of the cat and states of the nucleus: This is what we want. We also critique one previously claimed resolution of the measurement problem and seven previously claimed proofs that the measurement problem is unsolvable.This paper resolves the problem of definite outcomes, also known as "Schrodinger's cat" and the "problem of wavefunction collapse."

Reinterpreting Schrodinger's Cat Through the Informational Observer Framework

Greco, Giuseppe Junior

Schrodinger's cat is traditionally presented as a paradox highlighting the tension between quantum superposition and classical observation. Standard interpretations invoke either a fundamental wavefunction collapse, ontological branching of universes, or subjective Bayesian updating. In this paper, we propose a reinterpretation grounded in the Informational Observer Framework, according to which the paradox does not originate from an ontological superposition of macroscopic states, but from an unresolved informational configuration at the observer level. The cat itself is never simultaneously alive and dead; rather, the observer remains in a state of informational compression prior to interaction. Within this framework, wavefunction collapse is reinterpreted as an observer-level informational phase transition, not as a fundamental physical discontinuity. This approach preserves macroscopic realism, avoids ontological inflation, and reframes the measurement problem as an emergent informational phenomenon.Schrodinger's cat is traditionally presented as a paradox highlighting the tension between quantum superposition and classical observation.
