Erratum: Sufficient conditions and constraints for reversing general quantum errors [Phys. Rev. A 102 , 062415 (2020)]

Entanglement Survives Most Measurements

“…But much of our theory relies on our assumed perfection of measurements and with the recent thermodynamic concerns, it is important to try to understand the practicality and implications. For example, initial system-environment correlations cause complications when defining a map for the system evolution [8][9][10][11][12] and can result in temporally correlated errors and/or non-Markovian evolutions that can imply restrictions on error correction methods [13][14][15][16][17][18]. So, does a non-perfectly projective measurement leave a state entangled, or otherwise correlated with other states?…”
