On distilling secure key from reducible private states and (non)existence of entangled key-undistillable states
Hereunder, we study the class of irreducible private states that are private states from which all the secret content is accessible via measuring their key part. We provide the first protocol which distills key not only from the key part, but also from the shield if only the state is reducible. We p...
