Entangling quantum measurements and their properties
B. A. Grishanin, Victor N. Zadkov · Physical Review A · 2003
We study the mathematical structure of superoperators describing quantum measurements, including the entangling measurement---the generalization of the standard quantum measurement that results in entanglement between the measurable system and apparatus. It is shown that the coherent information can be effectively used for the analysis of such entangling measurements whose possible applications are discussed as well.
