Quantum Maps Between CPTP and HPTP
Ningping Cao, Maxwell Fitzsimmons, Zachary Mann +2
For an open quantum system to evolve under CPTP maps, assumptions are made on the initial correlations between the system and the environment. Hermitian-preserving trace-preserving…
Chordal Graphs and Distinguishability of Quantum Product States
Comfort Mintah, David W. Kribs, Michael Nathanson +1
We investigate a graph-theoretic approach to the problem of distinguishing quantum product states in the fundamental quantum communication framework called local operations and cla…
Absolutely -Incoherent Quantum States and Spectral Inequalities for Factor Width of a Matrix
Nathaniel Johnston, Shirin Moein, Rajesh Pereira +1
We investigate the set of quantum states that can be shown to be -incoherent based only on their eigenvalues (equivalently, we explore which Hermitian matrices can be shown to h…
Operator and Graph Theoretic Techniques for Distinguishing Quantum States via One-Way LOCC
Comfort Mintah, David W. Kribs, Michael Nathanson +1
We bring together in one place some of the main results and applications from our recent works in quantum information theory, in which we have brought techniques from operator theo…
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…
Birkhoff-James Orthogonality in the Trace Norm, with Applications to Quantum Resource Theories
Nathaniel Johnston, Shirin Moein, Rajesh Pereira +1
We develop numerous results that characterize when a complex Hermitian matrix is Birkhoff-James orthogonal, in the trace norm, to a (Hermitian) positive semidefinite matrix or set…
