Quantum walks in the density operator picture
Chaobin Liu
A new approach to quantum walks is presented. Considering a quantum system undergoing some unitary discrete-time evolution in a directed graph G, we think of the vertices of G as s…

On the behavior of quantum walks confined to a cycle coupled with a half line
Forrest Ingram-Johnson, Chaobin Liu, Nelson Petulante
When confined to a topological environment consisting of a cycle coupled with a half-line, quantum walks exhibit long-term statistical tendencies which differ dramatically from the…

From open quantum walks to unitary quantum walks
Chaobin Liu
We present an idea to convert to a unitary quantum walk any open quantum walk which is defined on lattices as well as on finite graphs. This approach generalizes to the domain of o…
