Explore cutting-edge research on magnetically levitated diamond crystals as a platform for investigating quantum mechanics and gravity interactions in this 19-minute conference talk. Learn about the development of a hybrid magneto-gravitational trap system that uses micron-scale diamond particles containing nitrogen-vacancy (NV) centers to achieve exceptional environmental isolation and long-lived mechanical coherence. Discover how researchers coherently couple NV center spins to center-of-mass motion through magnetic field gradients to prepare non-classical superposition states and study their decoherence over time. Examine the unique quantum sensing capabilities provided by built-in spin sensors for motion preparation and readout, while understanding how the gravity-dependent mechanical oscillation frequency opens new possibilities for quantum-enhanced gravimetry. Review recent advances in trap design, quantum-limited optical measurements, spin control, and motional state preparation techniques. Understand how this innovative approach enables measurement of position-space decoherence and could facilitate future tests of gravitational effects on quantum systems at mesoscopic scales, representing a significant step toward probing foundational questions at the quantum-gravity interface through table-top experiments.
