Digital noise spectroscopy with a quantum sensor
Guoqing Wang, Yuan Zhu, Boning Li +4
We introduce and experimentally demonstrate a quantum sensing protocol to sample and reconstruct the auto-correlation of a noise process using a single-qubit sensor under digital c…
Communication-efficient Quantum Algorithm for Distributed Machine Learning
Hao Tang, Boning Li, Guoqing Wang +5
The growing demands of remote detection and increasing amount of training data make distributed machine learning under communication constraints a critical issue. This work provide…
Characterizing temperature and strain variations with qubit ensembles for their robust coherence protection
Guoqing Wang, Ariel Rebekah Barr, Hao Tang +5
Solid-state spin defects, especially nuclear spins with potentially achievable long coherence times, are compelling candidates for quantum memories and sensors. However, their curr…
A geometric perspective: experimental evaluation of the quantum Cramer-Rao bound
Changhao Li, Mo Chen, Paola Cappellaro
The power of quantum sensing rests on its ultimate precision limit, quantified by the quantum Cramer-Rao bound (QCRB), which can surpass classical bounds. In multi-parameter estima…
