Playing Bayesian games better with separable quantum states than with any classical correlation
Yaqing Xy Wang, Giannicola Scarpa, Andreas Winter
Bayesian games, also known as games of incomplete information, are a fruitful arena for exploring the impact of correlations on a set of independent agents (players) via the game e…

Entanglement in bipartite X-states: Analytical results for the volume of states with positive partial transpose
Yaqing Xy Wang, József Zsolt Bernád
We provide an analytical formula for the volume ratio between bipartite X-states with positive partial transpose and all bipartite X-states. The result applies to arbitrary $m \tim…
