AbstractIn this note, we discuss a general definition of quantum random walks on graphs and illustrate with a simple graph the possibility of very different behavior between a classical random walk and its quantum analog. In this graph, propagation between a particular pair of nodes is exponentially faster in the quantum case. PACS: 03.67.Hk

Quantum Random Walks
The notion of a quantum random walk has received notable attention recently from the field of quantum information, revealing many surprising and subtle properties that range from significant speedupsExpand
Continuous-Time Quantum Walks on the Symmetric Group
• Mathematics, Physics
• RANDOM-APPROX
• 2003
It is shown that for several natural choices for generating sets, quantum walks on Cayley graphs of the symmetric group do not have uniform limiting distributions, and are effectively blind to large areas of the graphs due to destructive interference. Expand
An Analysis of Absorbing Times of Quantum Walks
• Computer Science
• UMC

We show that the hitting time of the discrete time quantum random walk on the n-bit hypercube from one corner to its opposite is polynomial in n. This gives the first exponential quantum-classicalExpand
Two Photon Quantum Walks
Classical random walks are a stochastic model of a particle or walker, moving according to classical physics about a discrete space represented by a combinatoric graph—a set of verticesExpand
