Towards Global Quantum Key Distribution
Haoran Zhang, Haotao Zhu, Ruihua He +4
Quantum Key Distribution (QKD) supports the negotiation and sharing of private keys with unconditional security between authorized parties. Over the years, theoretical advances and…
Optimal Overlapping Tomography
Kiara Hansenne, Rui Qu, Lisa T. Weinbrenner +7
Characterising large-scale quantum systems is central to fundamental physics and essential for applications of quantum technologies. While a full characterisation requires exponent…
Quantum Sensing Enhancement through a Nuclear Spin Register in Nitrogen-Vacancy Centers in Diamond
Jonathan Kenny, Feifei Zhou, Ruihua He +3
Quantum sensing has seen rapid progress from laboratory research to real-world applications. Solid-state spin systems, particularly nitrogen-vacancy (NV) centers in diamond, are at…
Quantum machine learning for multiclass classification beyond kernel methods
Chao Ding, Shi Wang, Yaonan Wang +1
Quantum machine learning is considered one of the current research fields with immense potential. In recent years, HavlÃÄek et al. [Nature 567, 209-212 (2019)] have proposed a qu…
