Abstract
We provide a new extension of entanglement witnesses for Cd1⊗Cd2 systems. Our construction preserves the properties of nondecomposability 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.
