| Abstract | We provide a recurrent construction of entanglement witnesses for a bipartite systems living in a Hilbert space corresponding to 2N qubits (N qubits in each subsystem). Our construction provides a method of generalization of the Robertson map that naturally meshes with 2N-qubit systems, i.e., its structure respects the 2[superscript 2N] growth of the state space. We prove that for N>1 these witnesses are indecomposable and optimal. As a byproduct we provide a family of PPT (Positive Partial Transpose) entangled states. |
