Quantum Information Science with Spins, Photons, Magnons, and Superconductors

Explore groundbreaking quantum platforms and experiments in this seminar lecture that delves into the hybridization of superconducting resonator photons and magnons, along with discoveries of new spin defects in GaN. Learn about the integration of thin-film superconducting resonators with low-damping V[TCNE]x microstructures, achieving strong coupling regime with high cooperativity suitable for quantum circuit integration. Discover two distinct defect species in GaN exhibiting optically detected magnetic resonance (ODMR), including one with room temperature ODMR contrast of ~5% and another with up to ~30% contrast. Understand the characterization of defect symmetry axes and spin Hamiltonians, while considering the implications of GaN's nuclear spin bath and the potential for quantum sensors integrated with electronics. Gain insights from Greg Fuchs, a Cornell University Applied and Engineering Physics professor whose research bridges magnetism and quantum information science, including quantum sensing, magneto-thermal microscopy, cavity/quantum magnonics, and hybrid spin-acoustic quantum systems.
