Fuzzy-processing quantum computation
Yan-Xiong Du
Quantum computation has attracted numerous attentions and develops rapidly in the recent decades. To against the decoherence and the control errors upon the qubits, quantum error c…
Measurement of non-Abelian gauge fields using multi-loop amplification
Qing-Xian Lv, Hong-Zhi Liu, Yan-Xiong Du +7
Non-Abelian gauge field (NAGF) plays a central role in understanding the geometrical and topological phenomena in physics. Here we experimentally induce a NAGF in the degenerate ei…
Synthetic Topological Vacua of Yang-Mills Fields in Bose-Einstein Condensates
Jia-Zhen Li, Cong-Jun Zou, Yan-Xiong Du +7
Topological vacua are a family of degenerate ground states of Yang-Mills fields with zero field strength but nontrivial topological structures. They play a fundamental role in part…
Measurement of spin Chern numbers in quantum simulated topological insulators
Qing-Xian Lv, Yan-Xiong Du, Zhen-Tao Liang +9
The topology of quantum systems has become a topic of great interest since the discovery of topological insulators. However, as a hallmark of the topological insulators, the spin C…
Accelerating geometric quantum gates through non-cyclic evolution and shortcut to adiabaticity
Qing-Xian Lv, Zhen-Tao Liang, Hong-Zhi Liu +3
Fast and robust quantum gates is the cornerstone of fault-tolerance quantum computation. In this paper, we propose to achieve quantum gates based on non-cyclic geometric evolution.…
Coherent population transfer via state-independent quasi-adiabatic dynamics
Jian Xu, Yan-Xiong Du, Wei Huang
High-fidelity and robust coherent population transfer is a major challenge in coherent quantum control. Different from the well known adiabatic condition, we present a rigorous adi…
Detecting topological exceptional points in a parity-time symmetric system with cold atoms
Jian Xu, Yan-Xiong Du, Wei Huang +1
We reveal a novel topological property of the exceptional points in a two-level parity-time symmetric system and then propose a scheme to detect the topological exceptional points…
Proposal for implementing universal superadiabatic geometric quantum gates in nitrogen-vacancy centers
Zhen-Tao Liang, Xianxian Yue, Qingxian Lv +4
We propose a feasible scheme to implement a universal set of quantum gates based on geometric phases and superadiabatic quantum control. Consolidating the advantages of both strate…
