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…
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…
Limit theorems for discrete-time quantum walks on trees
Kota Chisaki, Masatoshi Hamada, Norio Konno +1
We consider a discrete-time quantum walk W_t given by the Grover transformation on the Cayley tree. We reduce W_t to a quantum walk X_t on a half line with a wall at the origin. Th…
