Integrated quantum photonics developed with and for quantum hardware

The emitter-cavity interaction in solid state systems is governed by physics that can both make an impact on as well as benefit from the development of quantum hardware. In one direction, systems with color center integrated in photonic devices promise to build out quantum repeaters and analog quantum simulators of condensed matter and particle physics phenomena. To meet the scalability aspect for practical applications, we develop the first wafer-scale fabrication process in quantum-grade silicon carbide [1-3]. Reversely, to properly engineer envisioned photonic systems we pursue to deepen our understanding of open quantum system cavity QED in innovative ways using the emerging quantum computing hardware. To this goal, we develop analog and digital simulation of the open Tavis-Cummings model and test it on the DOE quantum testbeds [4-6], exploring this niche application for the near-term computational advantage.
