Abstract

Abstract We show that the non-positive maps used by authors are uniquely defined in terms of positive maps. This way we restore the well known result that entanglement witnesses are fully characterized by positive maps which are not completely positive.

Characterization of optimal entanglement witnesses

Xiaofei Qi, Jinchuan Hou

In this paper, we present a characterization of optimal entanglement witnesses in terms of positive maps and then provide a general method of checking optimality of entanglement witnesses. Applying it, we obtain indecomposable optimal witnesses that have no spanning property. These also provide examples that support a recent conjecture saying that the so-called structural physical approximations to optimal positive maps (optimal entanglement witnesses) give entanglement breaking maps (separable states).

Optimal indecomposable witnesses without extremality or the spanning property

Kil-Chan Ha, Hoseog Yu

One of the interesting problems of optimal indecomposable entanglement witnesses is whether there exists an optimal indecomposable entanglement witness which neither has the spanning property nor is associated with an extremal positive linear map. Here, we answer this question in the negative by examining the extremality of the positive linear maps constructed by Qi and Hou (2011 J. Phys. A: Math. Theor. 44 215305).

Using non-positive maps to characterize entanglement witnesses

Marek Mozrzymas, A. Rutkowski, Michał Studziński

In this paper we present a new method for entanglement witnesses construction. We show that to construct such an object we can deal with maps which are not positive on the whole domain, but only on a certain sub-domain. In our approach a crucial role is played by such maps which are surjective between sets of rank projectors and the set of rank one projectors acting in the d dimensional space. We argue that our method can be used to check whether a given observable is an entanglement witness. In the second part of this paper we show that an inverse reduction map satisfies this requirement and using it we can obtain a bunch of new entanglement witnesses.

Some Remarks on the Role of Minimal Length of Positive Maps in Constructing Entanglement Witnesses

Andrzej Jamiołkowski

The main objective of this paper is to discuss correspondence between the concept of entanglement witnesses (self-adjoint operators on a composite Hilbert space [Formula: see text] that are, in general, not positive, but are positive on separable states) and positive maps [Formula: see text] which are not completely positive. The notion of minimal length of linear positive map is introduced and the role of this quantity in the constructing of entanglement witnesses is explained.

Spectral conditions for positive maps and entanglement witnesses

Dariusz Chruściński, Andrzej Kossakowski

We provide partial classification of entanglement witnesses and positive maps which is based on a family of spectral conditions. Interestingly many well known examples of positive maps (e.g. transposition, reduction map, the family of Choi maps) belong to the class constructed via spectral conditions.
