Tracial embeddable strategies: Lifting MIP* tricks to MIPco

IQC-QuICS MATH CS Seminar - Junqiao (Randy) Lin, CWI, Amsterdam

Tracial embedded strategies are a subset of the commuting operator strategies that, in a quantum information sense, have many similarities to a finite-dimensional tensor product strategy. In this talk, I will introduce this set of strategies and sketch the proof that this set of strategies can approximate every strategy in the commuting operator model. Using this new characterization, I will discuss two ingredients for proving MIP*, robust EPR testing and the "rounding" theorem, and how they can be generalized to hold for MIPco. This talk is based on the paper arxiv.org/2304.01940 .
