Solving excited states for long-range interacting trapped ions with neural networks
Yixuan Ma, Chang Liu, Weikang Li +4
The computation of excited states in strongly interacting quantum many-body systems is of fundamental importance. Yet, it is notoriously challenging due to the exponential scaling…
Scalable and modular generation of multipartite entangled states through memory-enhanced fusion
Jixuan Shi, Sheng Zhang, Yukai Wu +5
Efficient generation of large-scale multipartite entangled states is a critical but challenging task in quantum information processing. Although generation of multipartite entangle…
Performance Analysis for Crosstalk Errors between Parallel Entangling Gates in Trapped Ion Quantum Error Correction
Fangxuan Liu, Gaoxiang Tang, Luming Duan +1
The ability to execute a large number of quantum gates in parallel is a fundamental requirement for quantum error correction, allowing an error threshold to exist under the finite…
Robust Mølmer-Sørensen Gate Against Symmetric and Asymmetric Errors
Wenhao Zhang, Gaoxiang Tang, Kecheng Liu +4
To achieve the entangling gate fidelity above the quantum error correction threshold, it is critical to suppress errors due to experimental imperfection. We consider the Mølmer-SÅ
Observation of quantum superposition of topological defects in a trapped ion quantum simulator
Zhijie Cheng, Yukai Wu, Shijiao Li +8
Topological defects are discontinuities of a system protected by global properties, with wide applications in mathematics and physics. While previous experimental studies mostly fo…
Experimental realization of direct entangling gates between dual-type qubits
Chenxi Wang, Chuanxin Huang, Hongxuan Zhang +6
Dual-type qubits have become a promising way to suppress the crosstalk error of auxiliary operations in large-scale ion trap quantum computation. Here we demonstrate a direct entan…
