Photonic Topological Baths for Quantum Simulation

Quantum simulation involves engineering devices to implement different Hamiltonians and measuring their quantized spectra to study quantum many-body systems. Recent developments in topological photonics have shown the possibility of studying novel quantum phenomena by controlling the topological properties of such devices. Here, using coupled arrays of up to 16 high Q silicon nanocavities, we experimentally realize quantum photonic baths, which are analogs of the Su-Schrieffer-Heeger model. We investigate the effect of fabrication-induced disorder on these baths by probing individual supermodes. We further demonstrate the design mitigation steps required to overcome the disorder effects in photonic cavities to simulate quantum systems.
