Checking the optimality of entanglement witnesses: an application to structural physical approximations
R. Augusiak, J. Bae, J. Tura +1
In 2008, the conjecture that structural physical approximations to optimal entanglement witnesses are separable states (in general unnormalized) was posed. In an attempt to disprov…

Optimal approximate transpose map via quantum designs and its applications to entanglement detection
Amir Kalev, Joonwoo Bae
We show that quantum designs characterize the general structure of the optimal approximation of the transpose map on quantum states. Based on this characterization, we propose an i…
