WebI believe I understand the concept of maximally mixed - it just means that the state is descibed by an ensemble with every possible quantum state having the same probability (in some sense it describes the most random ensemble one can have with a certain basis of quantum states). WebSince entangled states created in the laboratory typically have imperfections, it becomes important to understand the rates at which imperfectly entangled states may be distilled to maximally entangled ones, and this rate is a direct measure of the usefulness of the given state for many purposes.
