Limit distribution of a time-dependent 3-period quantum walk
Takuya Machida (JSPS)
Abstract (in Japanese) (See Japanese page) 
(in English) Quantum walks are quantum analogs of random walks and have a background of quantum physics. Also, their applications have largely headed for quantum computers. From the view point of mathematics, the long-time limit theorems of quantum walks have been studied to mention the behavior of the walker after a lot of evolutions. In this paper, our focus is put on a discrete-time quantum walk on the line. The walker determines its evolution by unitary operators which are chosen depending on time. The new result presented this time is a long-time limit distribution for a 3-period time-dependent quantum walk. The limit distribution shows an interesting behavior which we have never seen in a time-independent quantum walk or a 2-period time-dependent quantum walk. This is a joint work with F. Alberto Grunbaum (University of California, Berkeley) [1].
