Semidefinite programming relaxations for quantum correlations
Semidefinite programs are convex optimization problems involving a linear objective
function and a domain of positive-semidefinite matrices. Over the past two decades, they …

Estimating quantum chromatic numbers
We develop further the new versions of quantum chromatic numbers of graphs introduced by
the first and fourth authors. We prove that the problem of computation of the commuting …

A compositional approach to quantum functions
We introduce a notion of quantum function and develop a compositional framework for finite
quantum set theory based on a 2-category of quantum sets and quantum functions. We use …

On the power of PPT-preserving and non-signalling codes
D Leung, W Matthews - IEEE Transactions on Information …, 2015 - ieeexplore.ieee.org
We derive one-shot upper bounds for quantum noisy channel codes. We do so by regarding
a channel code as a bipartite operation with an encoder belonging to the sender and a …

Semidefinite programming strong converse bounds for classical capacity
We investigate the classical communication over quantum channels when assisted by no-
signaling and positive-partial-transpose-preserving (PPT) codes, for which both the optimal …

Quantum chromatic numbers via operator systems
We define several new types of quantum chromatic numbers of a graph and characterize
them in terms of operator system tensor products. We establish inequalities between these …

Graph-theoretic characterization of unextendible product bases
Unextendible product bases (UPBs) play a key role in the study of quantum entanglement
and nonlocality. Here we provide an equivalent characterization of UPBs in graph-theoretic …
