Programmable photonic system for quantum simulation in arbitrary topologies

Overview

This repository contains supporting simulations for the paper "Programmable photonic system for quantum simulation in arbitrary topologies". In this work, we describe a programmable photonic de- vice capable of emulating the dynamics of a broad class of Hamiltonians in lattices with arbitrary topologies and dimensions. We derive a correspondence between the physics of the device and the Hamiltonians of interest, and we simulate the physics of the device to observe a wide variety of phys- ical phenomena, including chiral states in a Hall ladder, effective gauge potentials, and oscillations in high-dimensional lattices. Our proposed device opens new possibilities for studying topological and many-body physics in near-term experimental platforms.
