Discrete Quantum Walks with Near-Term Neutral Atom Hardware Error Modelling — •Stephanie Foulds and Vivien Kendon — University of Strathclyde, Glasgow, UK

Quantum walks, the quantum analogue to the classical random walk, have been shown to be able to model fluid dynamics [1,2]. Neutral atom hardware is a promising choice of platform for implementing quantum walks due to its ability to implement native multiqubit gates and to dynamically re-arrange qubits [3]. Using error modelling for multiqubit Rydberg gates via two-photon adiabatic rapid passage [4], we present the gate sequences and final state fidelities for some toy quantum walks, including ’lazy’ quantum walks.
