Remarks on the Grothendieck norm

Thomas Sinclair, Naveen Vivek

The goal of this short note is to point out three observations around the Grothendieck norm and semidefinite programming. The first is that the Grothendieck norm captures the diffi…

An Index for Inclusions of Operator Systems

Roy Araiza, Colton Griffin, Thomas Sinclair

Inspired by a well-known characterization of the index of an inclusion of II factors due to Pimsner and Popa, we define an index-type invariant for inclusions of operator syste…

Approximating projections by quantum operations

Roy Araiza, Colton Griffin, Aneesh Khilnani +1

Using techniques from semidefinite programming, we study the problem of finding a closest quantum channel to the projection onto a matricial subsystem. We derive two invariants of…
