Spectral properties of circulant positive maps: classical versus quantum

Dariusz Chruściński

Published Jun 1, 2015• 0 citations

Abstract

A class of circulant stochastic matrices and positive maps in matrix algebras displaying circulant structure is analyzed. It is shown how the spectral properties of matrices and linear maps are related to positivity conditions. An interesting interplay between the classical and quantum case is revealed.

On pseudo-stochastic matrices and pseudo-positive maps

Dariusz Chruściński, Vladimir I. Man’ko, Giuseppe Marmo +1 more

Stochastic matrices and positive maps in matrix algebras have proved to be very important tools for analysing classical and quantum systems. In particular they represent a natural set of transformations for classical and quantum states, respectively. Here we introduce the notion of pseudo-stochastic matrices and consider their semigroup property. Unlike stochastic matrices, pseudo-stochastic matrices are permitted to have matrix elements which are negative while respecting the requirement that the sum of the elements of each column is one. They also allow for convex combinations, and carry a Lie group structure which permits the introduction of Lie algebra generators. The quantum analog of a pseudo-stochastic matrix exists and is called a pseudo-positive map. They have the property of transforming a subset of quantum states (characterized by maximal purity or minimal von Neumann entropy requirements) into quantum states. Examples of qubit dynamics connected with ‘diamond’ sets of stochastic matrices and pseudo-positive maps are dealt with.

On Kossakowski Construction of Positive Maps on Matrix Algebras

Dariusz Chruściński

We provide the continuation of an analysis of a class of positive maps proposed ten years ago by Kossakowski. In particular, we propose a new parametrization which reveals an elegant geometric structure and an interesting interplay between group theory and a certain class of positive maps.

Generalizing Choi map in M 3 beyond circulant scenario

Anindita Bera, Giovanni Scala, Gniewomir Sarbicki +1 more

We introduce a family of positive linear maps in the algebra of 3×3 complex matrices, which generalizes the seminal positive non-decomposable map originally proposed by Choi. Necessary and sufficient conditions for decomposability are derived and demonstrated. Specifically, the proposed maps evolve the circulant structure with three parameters into a doubly stochastic structure with five parameters.

Spectral properties of entanglement witnesses

Gniewomir Sarbicki

Entanglement witnesses are observables which when measured, detect entanglement in a measured composed system. It is shown what kind of relations between eigenvectors of an observable should be fulfilled, to allow an observable to be an entanglement witness. Some restrictions on the signature of entaglement witnesses, based on an algebraic-geometrical theorem will be given. The set of entanglement witnesses is linearly isomorphic to the set of maps between matrix algebras which are positive, but not completely positive. A translation of the results to the language of positive maps is also given. The properties of entanglement witnesses and positive maps express as special cases of general theorems for $k$-Schmidt witnesses and $k$-positive maps. The results are therefore presented in a general framework.

Spectral Properties of Circulant Quantum Markov Semigroups

Jorge R. Bolaños-Servín, Raffaella Carbone

We study the spectral properties of the generators of circulant quantum Markov semigroups. We can find an explicit expression for eigenvalues and eigenvectors of the infinitesimal generator and, in particular, we prove that the spectral gap is strictly positive. By proper techniques, we can reduce the problem on non-commutative algebras to the analogous one for a classical process with a circulant generator.

Characterization of Maps on Positive Semidefinite Choi Matrices

C. A. Winda, Benard Okelo, Omolo Ongati

Several investigations have been done on positive maps on their algebraic structures with more emphasis on completely positive maps. In this study, we have described the structure of the Choi matrices for 2-positive maps on positive semidefinite matrices and the conditions for complete positivity of positive linear maps from n to n+1. The motivation behind these objectives is work done by Majewski and Marciniak on the structure of positive maps ф from Mn to Mn + 1(2 ≥ 2) between matrix algebras.
