The Complete Positivity of Symmetric Tridiagonal and Pentadiagonal Matrices
Lei Cao, Darian McLaren, Sarah Plosker
We provide a decomposition that is sufficient in showing when a symmetric tridiagonal matrix is completely positive. Our decomposition can be applied to a wide range of matrice…
Complete Order Equivalence of Spin Unitaries
Douglas Farenick, Farrah Huntinghawk, Adili Masanika +1
This paper is a study of linear spaces of matrices and linear maps on matrix algebras that arise from \emph{spin systems}, or \emph{spin unitaries}, which are finite sets $\mathcal…
Bistochastic operators and quantum random variables
Sarah Plosker, Christopher Ramsey
Given a positive operator-valued measure acting on the Borel sets of a locally compact Hausdorff space , with outcomes in the algebra of all bounded…
Complex Hadamard Diagonalisable Graphs
Ada Chan, Shaun Fallat, Steve Kirkland +3
In light of recent interest in Hadamard diagonalisable graphs (graphs whose Laplacian matrix is diagonalisable by a Hadamard matrix), we generalise this notion from real to complex…
