New paper: Quantum walks with encrypted data

Download the full article here. In the setting of networked computation, data security can be a significant concern. Here we consider the problem of allowing a server to remotely manipulate client supplied data, in such a way that both the information obtained by the client about the server’s operation and the information obtained by the […]

New paper: A 2D Quantum Walk Simulation of Two-Particle Dynamics

This paper was recently published in Science. Download the full article here. Multi-dimensional quantum walks can exhibit highly non-trivial topological structure, providing a powerful tool for simulating quantum information and transport systems. We present a flexible implementation of a 2D optical quantum walk on a lattice, demonstrating a scalable quantum walk on a non-trivial graph […]
