Approximate factorization properties for operator systems
Roy Araiza, Larissa Kroell, Travis Russell +1
We show that many of the standard nuclearity properties considered in the literature for the hierarchy of operator system tensor products can be expressed as approximate factorizat…

Resource-Dependent Complexity of Quantum Channels
Roy Araiza, Yidong Chen, Marius Junge +1
We introduce a new framework for quantifying the complexity of quantum channels, grounded in a suitably chosen resource set. This class of convex functions is designed to analyze t…

Operator Systems Generated by Projections
Roy Araiza, Travis Russell
We construct a family of operator systems and -AOU spaces generated by a finite number of projections satisfying a set of linear relations. This family is universal in the sense…
