Incoherent operation
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 ]. Weboperations were proposed. We recall three classes of them: the maximally incoherent operations (MIOs) [7], the incoher-ent operations(IOs)[8], andthe strictly incoherentoperations (SIOs) [11, 12], which will be considered in this paper. The MIO is defined to be all operations Λ(ρ) = P N n=1 K nρK † such

(b) On the other hand, when the input state of S has any nonzero coherence, the ... Webcovariant incoherent operations, present a number of new coherent monotones based on relative R enyi entropies, and study incoherent state transformations under di erent operational classes. In particular, we derive necessary and su cient conditions for qubit state transformations and show these conditions hold for all classes of incoherent ...
WebAug 20, 2024 · Any incoherent state is of the form where are probability distribution. Any state which cannot be written as above form is defined as a coherent state, which means the coherence is basis-dependent. In the coherence resource theory framework proposed in [ … WebDec 23, 2016 · This approach is based on a simple principle: we demand that a genuinely incoherent operation preserves all incoherent states. This framework captures coherence under additional constrains such as energy preservation and all genuinely incoherent operations are incoherent regardless of their particular experimental realization.
