Entanglement of subspaces in terms of entanglement of superpositions
Gilad Gour, Aidan Roy
We investigate upper and lower bounds on the entropy of entanglement of a superposition of bipartite states as a function of the individual states in the superposition. In particul…
On the epistemic view of quantum states
Michael Skotiniotis, Aidan Roy, Barry C. Sanders
We investigate the strengths and limitations of the Spekkens toy model, which is a local hidden variable model that replicates many important properties of quantum dynamics. First,…
Two characterizations of crooked functions
Aidan Roy, Chris Godsil
We give two characterizations of crooked functions: one based on the minimum distance of a Preparata-like code, and the other based on the distance-regularity of a crooked graph.
Weighted complex projective 2-designs from bases: optimal state determination by orthogonal measurements
Aidan Roy, A. J. Scott
We introduce the problem of constructing weighted complex projective 2-designs from the union of a family of orthonormal bases. If the weight remains constant across elements of th…
