We construct the convex setMof two-qutrit states, and the subsetP⊂M. We characterize the extremal points of rank one and rank two of. We further show that the extremal points ofPhave rank not equaling to two, and at most six. We apply our results to a long-standing conjecture on ...
We then introduce two classes of quantum states: the assisted maximally coherent states and the assisted maximally entangled states. They can be transformed into maximally coherent or entangled pure states with the help of another party using local measurement and classical communication. We give ...
Additionally, we give worked examples and provide a large collection of tabulated multipartite MME states in a variety of systems. MME states are a special kind of maximally entangled mixed state (MEMS) for which every pure decomposition state in all decompositions is maximally entangled. Thus, ...
Mixed StatesBell InequalityRecently a class of maximally entangled states has been proposed that has the maximum amount of entanglement for a given purity. We investigate how much such states violate the conventional Bell inequality and discuss its implication....
We study extremal elements of the convex set of qubit-qutrit states whose marginals are maximally mixed. In the two qubit case, it is known that every extreme state of such a convex set is a maximally entangled pure state. In qubit-qutrit case, pure states do not exist in the convex ...
