WebMay 31, 2024 · The historically first and most general approach was suggested in [ 11 ], where the set of maximally incoherent operations (MIO) was considered. These are all operations which cannot create coherence, i.e., for any incoherent state . Another important family is the set of incoherent operations (IO) [ 12 ].
WebApr 27, 2024 · Incoherent operations, defined in terms of the Kraus decomposition, play an important role in state transformation.

Lett., 119 … WebSep 25, 2024 · Coherent superposition and entanglement are two fundamental aspects of nonclassicality. Here we provide a quantitative connection between the two on the level of operations by showing that the dynamical coherence of an operation upper bounds the dynamical entanglement that can be generated from it with the help of additional …
