Quantum walks - theory, application, and implementation

Wang Jingbo

School of Physics, The University of Western Australia

 

Abstract :      

Quantum walk represents a generalised version of the well-known classical random walk. Regardless of their apparent connection, the dynamics of a quantum walk is often non-intuitive and far deviate from its classical counterpart.  A multi-particle quantum walk presents an even richer dynamicalsystem due to intrinsic quantum correlations such as entanglement. Current research is suggesting potential applications across a whole range of different fields.  In this talk, I will give a brief introduction to quantum walks, discuss their potential applications, and consider everal physical implementation schemes.

Brief Introduction :

Jingbo Wang is a professor in the School of Physics at The University of Western Australia.  Her research spans several distinct disciplines including quantum dynamics theory, quantum computation and information, atomic and molecular physics, quantum chemistry, nanotechnology, acoustics and computational physics. Professor Wang received her Ph.D. degree in 1989 from the Department of Physics and Mathematical Physics, Adelaide University. She has published extensively, including a recent book by Springer, one edited special journal issue by American Scientific Publishers, four book chapters by Academic Press, Nova Science Publishers and American Scientific Publishers, as well as more than 160 research papers in prestigious physics journals and international conference proceedings.  Professor Wang currently leads the quantum dynamics and computation group at The University of Western Australia. She and her research team were the first to show the power of quantum walks in distinguishing a wide range of non-isomorphic graph classes and in extracting local and global structural information of complex networks. Her recent work has provided the most efficient quantum circuits to implement a large variety of quantum walks. She has also developed some of the best numerical techniques to solve problems of practical importance in both quantum and classical regimes
