Optimality of generalized Choi maps in $M_{3}$

Giovanni Scala, Anindita Bera, Gniewomir Sarbicki +1

A family of linear positive maps in the algebra of $3 \times 3$ complex matrices proposed recently in Bera et al. arXiv:2212.03807 is further analyzed. It provides a generalization…

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,…

Detecting Entanglement by State Preparation and Local Measurements

Jaemin Kim, Anindita Bera, Dariusz Chruściński +1

Entanglement witnesses (EWs) are a collection of observables that can characterize separable states and, experimentally, estimating EWs can verify entangled states. In this work, w…
