Quantum Walks in the Normalized Laplacian
Gabriel Coutinho, Pedro Ferreira Baptista
We provide a characterization of perfect state transfer in a quantum walk whose Hamiltonian is given by the normalized Laplacian. We discuss a connection between classical random w…
Why and how to add direction to a quantum walk
Rodrigo Chaves, Bruno Oliveira Chagas, Gabriel Coutinho
We formalize the treatment of directed (or chiral) quantum walks using Hermitian adjacency matrices, bridging two developing fields of research in quantum information and spectral…
Perfect State Transfer in a Spin Chain without Mirror Symmetry
Gabriel Coutinho, Luc Vinet, Hanmeng Zhan +1
We introduce an analytical spin chain with asymmetrical transport properties. It has an even number of sites labeled by . It does not exhibit perfect state…
Quantum Fractional Revival on Graphs
Ada Chan, Gabriel Coutinho, Christino Tamon +2
Fractional revival is a quantum transport phenomenon important for entanglement generation in spin networks. This takes place whenever a continuous-time quantum walk maps the chara…
