Abstract:

Positive semidefinite (PSD) rank is a concept that was proposed recently to study the computational power of semidefinite programming, a problem in optimization theory. It turns out that it also has nontrivial applications in quantum information theory and even quantum foundations. In this talk, we will briefly introduce this quantity and its applications in device-independent quantum tasks.
