Abstract

Description

Four qubit bound entangled Smolin states are generalised in a natural way to even number of qubits. They are shown to maximally violate simple correlation Bell inequalities and, as such, to reduce communication complexity, though they do not admit quantum security. They are also shown to serve for remote quantum information concentration like in the case of the original four qubit states. Application of the information concentration to the process of unlocking of classical correlations and quantum entanglement by quantum bit is pointed out.
