Probing the dynamical phase transition with a superconducting quantum simulator
Kai Xu, Zheng-Hang Sun, Wuxin Liu +9
Non-equilibrium quantum many-body systems, which are difficult to study via classical computation, have attracted wide interest. Quantum simulation can provide insights into these…
Contributions of box diagrams and resonance to photoproduction
Xuyang Liu, Daris Samart, Kai Xu +3
We study first the box-diagram contribution to the process to understand the anomaly of the kaon photoproduction cross section from CBELSA/TAPS experimen…
Experimental demonstration of entanglement-enabled universal quantum cloning in a circuit
Zhen-Biao Yang, Pei-Rong Han, Xin-Jie Huang +6
No-cloning theorem forbids perfect cloning of an unknown quantum state. A universal quantum cloning machine (UQCM), capable of producing two copies of any input qubit with the opti…
Breakdown of Raman Selection Rules By Fröhlich Interaction in Few-Layer WS
Qing-Hai Tan, Kai-Xuan Xu, Yu-Jia Sun +5
The Raman selection rules arise from the crystal symmetry and then determine the Raman activity and polarization of scattered phonon modes. However, these selection rules can be br…
Complete basis for the pentaquark wave function in a group theory approach
Kai Xu, Attaphon Kaewsnod, Xuyang Liu +3
Permutation groups are applied to analyze the symmetries of pentaquark states. All possible quark configurations of the color, flavor, spin and spatial degrees of freedom are worke…
Quantum dynamical speedup in correlated noisy channels
Kai Xu, Guo-Feng Zhang, Wu-Ming Liu
The maximal evolution speed of a quantum system can be represented by quantum speed limit time (QSLT).We investigate QSLT of a two-qubit system passing through a correlated channel…
