Tensor product extension of entanglement witnesses and their connection with measurement device independent entanglement

Abstract

We provide a new extension of entanglement witnesses for ${\mathbb{C}}^{d_1}\otimes {\mathbb{C}}^{d_2}$ systems. Our construction preserves the properties of indecomposability and spanning property of entanglement witnesses. We show how our concept of extended entanglement witnesses is connected with the idea of measurement device independent entanglement witnesses.
