Correcting Quantum Errors with Entanglement
Todd Brun, Igor Devetak, Min-Hsiu Hsieh
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require…

Quantum walks with infinite hitting times
Hari Krovi, Todd A. Brun
Hitting times are the average time it takes a walk to reach a given final vertex from a given starting vertex. The hitting time for a classical random walk on a connected graph wil…

Hypersensitivity and chaos signatures in the quantum baker's maps
A. J. Scott, Todd A. Brun, Carlton M. Caves +1
Classical chaotic systems are distinguished by their sensitive dependence on initial conditions. The absence of this property in quantum systems has lead to a number of proposals f…
