Entanglement Breaking Channels, Stochastic Matrices, and Primitivity
Jennifer Ahiable, David W. Kribs, Jeremy Levick +2
We consider the important class of quantum operations (completely positive trace-preserving maps) called entanglement breaking channels. We show how every such channel induces stoc…
An extension of Bravyi-Smolin's construction for UMEBs
Jeremy Levick, Mizanur Rahaman
We extend Bravyi and Smolin's construction for obtaining unextendible maximally entangled bases (UMEBs) from equiangular lines. We show that equiangular real projections of rank mo…
Nullspaces of Entanglement Breaking Channels and Applications
D. W. Kribs, J. Levick, K. Olfert +2
We investigate the nullspace structures of entanglement breaking channels, and related applications. We show that every operator space of trace zero matrices is the nullspace of an…
Approximate Quasiorthogonality of Operator Algebras and Relative Quantum Privacy
David W. Kribs, Jeremy Levick, Mike Nelson +2
We show that the approximate quasiorthogonality of two operator algebras is equivalent to the algebras being approximately private relative to their conditional expectation quantum…
Bisynchronous Games and Factorizable Maps
Vern I. Paulsen, Mizanur Rahaman
We introduce a new class of non-local games, and corresponding densities, which we call bisynchronous. Bisynchronous games are a subclass of synchronous games and exhibit many inte…
Quantum Complementarity and Operator Structures
D. W. Kribs, J. Levick, M. I. Nelson +2
We establish operator structure identities for quantum channels and their error-correcting and private codes, emphasizing the complementarity relationship between the two perspecti…
