Relations between coherence and path information
Emilio Bagan, Janos A. Bergou, Seth S. Cottrell +1
We find two relations between coherence and path-information in a multi-path interferometer. The first builds on earlier results for the two-path interferometer, which used minimum…
A Simple Method for Finding the Scattering Coefficients of Quantum Graphs
Seth S. Cottrell
Quantum walks are roughly analogous to classical random walks, and like classical walks they have been used to find new (quantum) algorithms. When studying the behavior of large gr…
Finding Structural Anomalies in Star Graphs Using Quantum Walks: A General Approach
Seth S. Cottrell
In previous papers about searches on star graphs several patterns have been made apparent; the speed up only occurs when graphs are "tuned" so that their time step operators have d…
Finding structural anomalies in star graphs: A general approach
Seth Cottrell, Mark Hillery
We develop a general theory for a quantum-walk search on a star graph. A star graph has N edges each of which is attached to a central vertex. A graph G is attached to one of these…
