Single-Ensemble Multiparameter Squeezing with Qudits
Xiaoshui Lin, Chunlei Qu, Chong Zu +1
Conventional spin squeezing enhances a single sensing channel. Here, we show how internal qudit levels enable simultaneous multiparameter squeezing within one ensemble. In two-comp…
Qubit Noise Spectroscopy of Superconducting Dynamics in a Magnetic Field
Jiajie Cheng, Jaewon Kim, Oriana K. Diessel +2
An applied magnetic field affects a superconductor in two ways -- by promoting pairing fluctuations, and by inducing topological defects called vortices that carry quantized magnet…
A Deep-Learning-Boosted Framework for Quantum Sensing with Nitrogen-Vacancy Centers in Diamond
Changyu Yao, Haochen Shen, Zhongyuan Liu +13
Nitrogen-vacancy (NV) centers in diamond are a versatile quantum sensing platform for high sensitivity measurements of magnetic fields, temperature and strain with nanoscale spatia…
Spin Relaxometry with Solid-State Defects: Theory, Platforms, and Applications
Ruotian Gong, Alex L. Melendez, Guanghui He +3
Spin relaxometry using solid-state spin defects, such as the diamond nitrogen-vacancy (NV) center, probes dynamical processes by measuring how environmental fluctuations enhance th…
Scalable Spin Squeezing in Power-Law Interacting XXZ Models with Disorder
Samuel E. Begg, Bishal K. Ghosh, Chong Zu +2
While spin squeezing has been traditionally considered in all-to-all interacting models, recent works have shown that it can also occur in systems with power-law interactions, enab…
