Crossovers induced by discrete-time quantum walks
Kota Chisaki, Norio Konno, Etsuo Segawa +1
We consider crossovers with respect to the weak convergence theorems from a discrete-time quantum walk (DTQW). We show that a continuous-time quantum walk (CTQW) and discrete- and…
Limit Theorems for the Discrete-Time Quantum Walk on a Graph with Joined Half Lines
Kota Chisaki, Norio Konno, Etsuo Segawa
We consider a discrete-time quantum walk at time on a graph with joined half lines , which is composed of half lines with the same origin. Our analy…
Localization of discrete-time quantum walks on a half line via the CGMV method
Norio Konno, Etsuo Segawa
We study discrete-time quantum walks on a half line by means of spectral analysis. Cantero et al. [1] showed that the CMV matrix, which gives a recurrence relation for the orthogon…
Emergence of Randomness and Arrow of Time in Quantum Walks
Yutaka Shikano, Kota Chisaki, Etsuo Segawa +1
Quantum walks are powerful tools not only to construct the quantum speedup algorithms but also to describe specific models in physical processes. Furthermore, the discrete time qua…
