Single-Ensemble Multiparameter Squeezing with Qudits
Xiaoshui Lin, Chunlei Qu, Chong Zu +1
Quantum-enhanced multiparameter sensing is often associated with distributed architectures or 2-anticoherent states, whereas squeezing in a single collective ensemble is typically…
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…
Unilateral Criticality and Phase Transition in the Cavity-Ising Model
Zeyu Rao, Xiaoshui Lin, Xiwang Luo +3
Superradiant phase transitions from cavity light-matter coupling have been widely explored across platforms. Here, we report a unilateral critical endpoint (UCEP) and a tricritical…
Cold atomic ensembles as quantum antennas for distributed networks of single-atom arrays
Xiaoshui Lin, Yefeng Mei, Chuanwei Zhang
Single neutral atoms in optical tweezer arrays offer a promising platform for high-fidelity quantum computing at local nodes. Nonetheless, creating entanglement between remote node…
Simulation of open quantum systems on universal quantum computers
Huan-Yu Liu, Xiaoshui Lin, Zhao-Yun Chen +8
The rapid development of quantum computers has enabled demonstrations of quantum advantages on various tasks. However, real quantum systems are always dissipative due to their inev…
Landau-Zener-Stückelberg interference in edge state pumping
Y. Liu, Xiaoshui Lin, Ming Gong
The adiabatic edge state pumping (ESP) in one dimensional model, which has important applications in topological phase transition and quantum simulation, has been widely performed…
