# Spin-Based Quantum Dot Quantum Computing

@article{Hu2004SpinBasedQD, title={Spin-Based Quantum Dot Quantum Computing}, author={Xuedong Hu}, journal={arXiv: Mesoscale and Nanoscale Physics}, year={2004} }

We present a brief overview of the current theoretical and experimental progresses in the study of quantum dot-based quantum computing schemes, then focus on the spin-based varieties, which are generally regarded as the most scalable because of the relatively long coherence times of electron and nuclear spins. Reviewed topics include spin coherence, spin interaction, spin detection, and the current status of the experimental studies of spin-based quantum computing.
