Proximate nitrogen-vacancy (NV) defects with inter-defect interaction may establish a new kind of quantum qubit network to explore controlled multi-body quantum dynamics. Especially, by introducing the critical distance and favorable orientation between a pair of NV defects, the quantum resonance (QR) can be induced. Here, we present the first real-time depolarization and phonon dynamics on the excited state at ambient temperature which are intrinsic to the proximate multi-NV defects. We computationally demonstrated that the QR can effectively change the major properties of the multi-NV defects such as orbital degeneracy, orbital delocalization, local phonon modes, electron-phonon coupling, and orbital depolarization dynamics, elucidating the physical mechanisms and finding the key factors to control them. The physical insights provide a starting point for the positioning accuracy of NV defects and creation protocols with broad implications for magnetometry, quantum information, nanophotonics, sensing and spectroscopy, letting the QR be a new kind of physical manipulation.
