Thermometry of Trapped Ions Based on Bichromatic Driving
Xie-Qian Li, Yi Tao, Ting Chen +4
Accurate thermometry of laser-cooled ions is crucial for the performance of the trapped-ions quantum computing platform. However, most existing methods face a computational exponen…
Mode-resolved thermometry of trapped ion with Deep Learning
Yi Tao, Ting Chen, Yi Xie +5
In trapped ion system, accurate thermometry of ion is crucial for evaluating the system state and precisely performing quantum operations. However, when the motional state of a sin…
Observation of quantum temporal correlations well beyond Luders bound
Chun-Wang Wu, Man-Chao Zhang, Yan-Li Zhou +10
Quantum correlations, both spatial and temporal, are the central pillars of quantum mechanics. Over the last two decades, a big breakthrough in quantum physics is its complex exten…
Characterizing the spatial potential of a surface electrode ion trap
Qingqing Qin, Ting Chen, Xinfang Zhang +6
The accurate characterization of the spatial potential generated by a planar electrode in a surface-type Paul trap is of great interest. To achieve this, we employ a simple yet hig…
Experimental violation of Leggett-Garg inequality in a three-level trapped-ion system
Tianxiang Zhan, Chunwang Wu, Manchao Zhang +9
Leggett-Garg inequality (LGI) studies the temporal correlation in the evolution of physical systems. Classical systems obey the LGI but quantum systems may violate it. The extent o…
Self-Testing of a Single Quantum System: Theory and Experiment
Xiao-Min Hu, Yi Xie, Atul Singh Arora +13
Certifying individual quantum devices with minimal assumptions is crucial for the development of quantum technologies. Here, we investigate how to leverage single-system contextual…
Parallel-Electromagnetically-Induced-Transparency Near Ground-State Cooling of a Trapped-ion Crystal
Jie Zhang, Man-Chao Zhang, Yi Xie +8
We theoretically propose and experimentally demonstrate a parallel-electromagnetically-induced transparency (parallel-EIT) cooling technique for ion crystals in the Paul trap. It h…
Investigation of the Effect of Quantum Measurement on Parity-Time Symmetry
Wei-Chen Wang, Yi Xie, Man-Chao Zhang +6
Symmetry, including the parity-time ()-symmetry, is a striking topic, widely discussed and employed in many fields. It is well-known that quantum measurement can dest…
Estimation of the Laser Frequency Nosie Spectrum by Continuous Dynamical Decoupling
Manchao Zhang, Yi Xie, Jie Zhang +5
Decoherence induced by the laser frequency noise is one of the most important obstacles in the quantum information processing. In order to suppress this decoherence, the noise powe…
