Entanglement entropy in two-particle Grover walks on graphs
Sho Kubota, Haruhiko Matsubara, Etsuo Segawa
We define a two-particle quantum walk of identical particles on a graph via the one-particle Grover walk on the Kronecker product , and call it the two-particle Gr…

A convergence time of Grover walk on regular graph to stationary state
Ayaka Ishikawa, Sho Kubota, Etsuo Segawa
We consider a quantum walk model on a finite graph which has an interaction with the outside. Here a quantum walker from the outside penetrates the graph and also a quantum walker…

A new type of spectral mapping theorem for quantum walks with a moving shift on graphs
Sho Kubota, Kei Saito, Yusuke Yoshie
The conventional spectral mapping theorem for quantum walks can only be applied for walks employing a shift operator whose square is the identity. This theorem gives most of the ei…
