Leggett-Garg macrorealism and the quantum nondisturbance conditions
Leggett-Garg macrorealism and the quantum nondisturbance conditions
We investigate the relation between a refined version of Leggett and Garg conditions for macrorealism, namely the no-signaling-in-time (NSIT) conditions, and the quantum mechanical notion of nondisturbance between measurements. We show that all NSIT conditions are satisfied for any state preparation if and only if certain compatibility criteria on the …
