A First-principles Computational Framework for Quantum Decoherence in Complex Diamond Spin Environments
Huijin Park, Ha-young Jeong, Hyeonsu Kim +6
Quantum decoherence induced by defects remains a major limitation for solid-state quantum technologies, yet predicting decoherence in realistic materials remains computationally ch…
Mesoscopic Spin Coherence in a Disordered Dark Electron Spin Ensemble
Taewoong Yoon, Sangwon Oh, Junghyun Lee +1
Harnessing dipolar spin environments as controllable quantum resources is a central challenge in solid-state quantum technologies. Here, we report the observation of a coherent mes…
Coherent control of solid-state defect spins via patterned boron-doped diamond circuit
Masahiro Ohkuma, Eikichi Kimura, Eunsang Lee +8
Monolithic integration, which refers to the incorporation of all device functionalities within a single material, shows significant potential for creating scalable solid-state quan…
Quantum decoherence of nitrogen-vacancy spin ensembles in a nitrogen spin bath in diamond under dynamical decoupling
Huijin Park, Mykyta Onizhuk, Eunsang Lee +5
The negatively charged nitrogen-vacancy (NV) center in diamond has emerged as a leading qubit platform for quantum technology applications. One of the key challenges for NV-based q…
