99.92%-Fidelity CNOT Gates in Solids by Filtering Time-dependent and Quantum Noises
Tianyu Xie, Zhiyuan Zhao, Shaoyi Xu +6
Inevitable interactions with the reservoir largely degrade the performance of non-local gates, which hinders practical quantum computation from coming into existence. Here we exper…
Spin Quantum Heat Engine Quantified by Quantum Steering
Wentao Ji, Zihua Chai, Mengqi Wang +6
Following the rising interest in quantum information science, the extension of a heat engine to the quantum regime by exploring microscopic quantum systems has seen a boom of inter…
Identity Test of Single NV Centers in Diamond at Hz-Precision Level
Tianyu Xie, Zhiyuan Zhao, Maosen Guo +3
Atomic-like defects in solids are not considered to be identical owing to the imperfections of host lattice. Here, we found that even under ambient conditions, negatively charged n…
Beating the Standard Quantum Limit under Ambient Conditions with Solid-State Spins
Tianyu Xie, Zhiyuan Zhao, Xi Kong +10
Precision measurement plays a crucial role in all fields of science. The use of entangled sensors in quantum metrology improves the precision limit from the standard quantum limit…
Super-resolution Localization of Nitrogen Vacancy Centers in Diamond with Quantum Controlled Photoswitching
Pengfei Wang, You Huang, Maosen Guo +7
We demonstrate the super-resolution localization of the nitrogen vacancy centers in diamond by a novel fluorescence photoswitching technique based on coherent quantum control. The…
Kilohertz electron paramagnetic resonance spectroscopy of single nitrogen centers at zero magnetic field
Fei Kong, Pengju Zhao, Pei Yu +6
Electron paramagnetic resonance spectroscopy (EPR) is among the most important analytical tools in physics, chemistry, and biology. The emergence of nitrogen-vacancy (NV) centers i…
