The main objective of this paper is to discuss correspondence between the concept of entanglement witnesses (self-adjoint operators on a composite Hilbert space H = H1⊗H2 that are, in general, not positive, but are positive on separable states) and positive maps Φ : L(H1) → L(H2) which are not completely positive. The notion of minimal length of linear(More)
