Limits on the ability of quantum states to convey classical messages
We revisit the problem of conveying classical messages by transmitting quantum states, and derive new, optimal bounds on the number of quantum bits required for this task. Much of...

Conductance of Armchair GNRs with side-attached organic molecules
In this work we show a theoretical study of the transport properties of armchair graphene nanoribbon at which linear poly-aromatic hydrocarbon molecules (LPHC) are side-attached o...

An efficient algorithm for positive realizations
We observe that successive applications of known results from the theory of positive systems lead to an efficient general algorithm for positive realizations of transfer functions...

Stability robustness in the presence of exponentially unstable isolated equilibria
This note studies nonlinear systems evolving on manifolds with a finite number of asymptotically stable equilibria and a Lyapunov function which strictly decreases outside equilibr...

An algebraic framework for quadratic invariance
In this paper, we present a general algebraic framework for analysing decentralized control systems. We consider systems defined by linear fractional functions over a commutative ...
