Complexity and capacity bounds for quantum channels
Rupert H. Levene, Vern I. Paulsen, Ivan G. Todorov
We generalise some well-known graph parameters to operator systems by considering their underlying quantum channels. In particular, we introduce the quantum complexity as the dimen…

Graph rigidity for unitarily invariant matrix norms
Derek Kitson, Rupert H. Levene
A rigidity theory is developed for bar-joint frameworks in linear matrix spaces endowed with a unitarily invariant norm. Analogues of Maxwell's counting criteria are obtained and m…
