Incoherent operation
WebFeb 22, 2024 · In the resource theory of quantum coherence, the free states are incoherent states, which can be diagonalized under a fixed reference basis [ 2 ]. Free operations (incoherent operations) are some specified classes of physically realizable operations [ 2 ]. WebThey could transform real existence into incoherent dreams. D. ... In the following statements about graph operations，which one is NOT correct? A．Finding critical path is an operation on directed graph. B．Finding critical path is an operation on undirected graph. C．Spanning tree of a graph may not be unique.
