Physics Seminar: Deep Microscopic Quantum Electrodynamics: Spotlight on Quantum Science and Technology
Sathwik Bharadwaj is a Research Scientist at the Birck Nanotechnology Center, Purdue University.
Abstract:
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 deep microscopic quantum electrodynamics (QED) framework coupled with scientific software development to unveil several sub-nanoscale optical phases of matter including hidden optical polarization texture, and light-induced topological phases of quantum materials. 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. Second, I will discuss the development of a full stack of multiscale computational QED framework to design hybrid quantum devices. I will show the applicability of the computational design guidelines to develop Nitrogen vacancy (NV) center-based quantum sensors, gate circuits for silicon and NV center-based quantum computing architectures, and superconducting single-photon detectors. Looking ahead, I will discuss how this computational quantum design framework establish a roadmap for advancing quantum computing, sensing, and communication.
