Approximately Clean Quantum Probability Measures
Douglas Farenick, Remus Floricel, Sarah Plosker
A quantum probability measure--or quantum measurement--is said to be clean if it cannot be irreversibly connected to any other quantum probability measure via a quantum channel. Th…

Schur multipliers and mixed unitary maps
Samuel J. Harris, Rupert H. Levene, Vern I. Paulsen +2
We consider the tensor product of the completely depolarising channel on matrices with the map of Schur multiplication by a correlation matrix and characte…

Some notes on the robustness of k-coherence and k-entanglement
Nathaniel Johnston, Chi-Kwong Li, Sarah Plosker +2
We show that two related measures of k-coherence, called the standard and generalized robustness of k-coherence, are equal to each other when restricted to pure states. As a direct…
