Quantum walking in curved spacetime: discrete metric
Pablo Arrighi, Giuseppe Di Molfetta, Stefano Facchini
A discrete-time quantum walk (QW) is essentially a unitary operator driving the evolution of a single particle on the lattice. Some QWs have familiar physics PDEs as their continuu…

The Elephant Quantum Walk
Giuseppe Di Molfetta, Diogo O. Soares-Pinto, Silvio M. Duarte Queiros
We explore the impact of long-range memory on the properties of a family of quantum walks in a one-dimensional lattice and discrete time, which can be understood as the quantum ver…
