Hidden nonmacrorealism: Reviving the Leggett-Garg inequality with stochastic operations
The Leggett-Garg inequality here (LGI) distinguishes nonmacrorealistic channels from macrorealistic ones by constraining the experimental outcomes of the underlying system.In this work, we propose a class of channels which, initially, cannot violate the LGI (in the form of the temporal Bell inequality) but can violate it after the application of st
