Spectral characterization of the uniform theta graph $Θ (t, 2)$ and classification of 6-periodic Grover walks

Sho Kubota

We characterize the uniform theta graph $Θ (t, 2)$ by the spectrum of its normalized adjacency matrix, or equivalently, by the spectrum of its normalized Laplacian matrix. We also in…

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 $G$ via the one-particle Grover walk on the Kronecker product $G \otimes G$ , and call it the two-particle Gr…
