Abstract

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 upto 16 high Q nano-cavities 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 super-modes and demonstrate the design mitigation steps required to overcome the disorder effects on the quantum phenomena.
