Quantum science and technology holds the potential to deliver transformative innovations in computing, ultra-precision measuring devices, and next-generation materials. In this talk, I will showcase a synergistic development of predictive computational strategies to guide the development of quantum technologies. First, I will discuss the development of a full stack of multiscale computational quantum electrodynamics frameworks to design hybrid quantum devices. I will show the applicability of the computational design guidelines to design gate circuits for silicon and nitrogen-vacancy center-based quantum computing architectures, superconducting single-photon detectors, and lossless infrared absorbers. Second, I will discuss the development of a deep microscopic quantum electrodynamics framework coupled with scientific software development for designing photonic materials for quantum communication systems. I will show how this photonic material design framework has led to the development of spectro-polarimetric imagers to capture hidden polarization data, spin-polarized infrared beacons for defense technology, and deep ultra-violet radiation sources for semiconductor metrology. Looking ahead, I will discuss how this computational quantum design framework establish a roadmap for advancing quantum computing, sensing, and communication.
