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…
A simplified and unified generalization of some majorization results
Shirin Moein, Rajesh Pereira, Sarah Plosker
We consider positive, integral-preserving linear operators acting on space, known as stochastic operators or Markov operators. We show that, on finite-dimensional spaces, any…
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…
Switching and partially switching the hypercube while maintaining perfect state transfer
Steve Kirkland, Sarah Plosker, Xiaohong Zhang
A graph is said to exhibit perfect state transfer (PST) if one of its corresponding Hamiltonian matrices, which are based on the vertex-edge structure of the graph, gives rise to P…
An operator-valued Lyapunov theorem
Sarah Plosker, Christopher Ramsey
We generalize Lyapunov's convexity theorem for classical (scalar-valued) measures to quantum (operator-valued) measures. In particular, we show that the range of a nonatomic quantu…
On Operator Valued Measures
Darian McLaren, Sarah Plosker, Christopher Ramsey
We consider positive operator valued measures whose image is the bounded operators acting on an infinite-dimensional Hilbert space, and we relax, when possible, the usual assumptio…
