Joint Unitarity and a Single Definite Outcome in a Quantum Measurement
Derives a lower bound on the dependence of the post-measurement environment state on the pre-measurement system state (conditioned on outcome) under joint unitarity assumptions, and suggests an experimental test for compatibility with definite outcomes.
