Pointer States Are Not Enough: Physical Monitor Selection in a Finite Quantum Register

Summary and scope

An exact finite register study separates available transitions, exported environment records and the resulting preserved coherences. Channels sharing the same exit edges can preserve different coherences, so transition support alone does not select the monitored channel. The stated polarity-resolved instrument distinguishes more labels than coarser alternatives. The result concerns these specified instruments on the owned register; a physical system–environment interaction selecting one of them remains an additional input.
