Optimizing positive maps in the matrix algebra $M_{n}$

Anindita Bera, Gniewomir Sarbicki, Dariusz Chruściński

We present an optimization procedure for a seminal class of positive maps $τ_{n, k}$ in the algebra of $n \times n$ complex matrices introduced and studied by Tanahasi and Tomiyama,…

A class of Bell diagonal entanglement witnesses in $C^{4} \otimes C^{4}$ : optimization and the spanning property

Anindita Bera, Filip A. Wudarski, Gniewomir Sarbicki +1

Two classes of Bell diagonal indecomposable entanglement witnesses in $C^{4} \otimes C^{4}$ are considered. Within the first class, we find a generalization of the we…
