Resource-efficient Direct Characterization of General Density Matrix
Liang Xu, Mingti Zhou, Runxia Tao +12
Sequential weak measurements allow the direct extraction of individual density-matrix elements instead of globally reconstructing the whole density matrix, opening a new avenue for…
Online optimization for optical readout of a single electron spin in diamond
Xue Lin, Jingwei Fan, Runchuan Ye +4
The nitrogen-vacancy (NV) center in diamond has been developed as a promising platform for quantum sensing, especially for magnetic field measurements in the nano-tesla range with…
Sensitivity-enhanced magnetometry using nitrogen-vacancy ensembles via adaptively complete transitions overlapping
Bao Chen, Bing Chen, Xinyi Zhu +3
Nitrogen-vacancy (NV) centers in diamond are suitable sensors of high-sensitivity magnetometry which have attracted much interest in recent years. Here, we demonstrate sensitivity-…
Preserving Entanglement in a Solid-Spin System Using Quantum Autoencoders
Feifei Zhou, Yu Tian, Yumeng Song +6
Entanglement, as a key resource for modern quantum technologies, is extremely fragile due to the decoherence. Here, we show that a quantum autoencoder, which is trained to compress…
Mixed-signal data acquisition system for optically detected magnetic resonance of solid-state spins
Feifei Zhou, Shupei Song, Yuxuan Deng +3
We report a mixed-signal data acquisition (DAQ) system for optically detected magnetic resonance (ODMR) of solid-state spins. This system is designed and implemented based on a Fie…
Noise prediction and reduction of single electron spin by deep-learning-enhanced feedforward control
Nanyang Xu, Feifei Zhou, Xiangyu Ye +7
Noise-induced control imperfection is an important problem in applications of diamond-based nano-scale sensing, where measurement-based strategies are generally utilized to correct…
