Study of charmonium-like and fully-charm tetraquark spectroscopy
Zheng Zhao, Kai Xu, Attaphon Kaewsnod +3
The masses of tetraquark states of all and quark configurations are evaluated in a constituent quark model, where the Cornell-like potential and…
Realizing a quantum generative adversarial network using a programmable superconducting processor
Kaixuan Huang, Zheng-An Wang, Chao Song +11
Generative adversarial networks are an emerging technique with wide applications in machine learning, which have achieved dramatic success in a number of challenging tasks includin…
Demonstration of a non-Abelian geometric controlled-Not gate in a superconducting circuit
Kai Xu, Wen Ning, Xin-Jie Huang +6
Holonomies, arising from non-Abelian geometric transformations of quantum states in Hilbert space, offer a promising way for quantum computation. These holonomies are not commutabl…
Observation of Bloch Oscillations and Wannier-Stark Localization on a Superconducting Processor
Xue-Yi Guo, Zi-Yong Ge, Hekang Li +9
The Bloch oscillation (BO) and Wannier-Stark localization (WSL) are fundamental concepts about metal-insulator transitions in condensed matter physics. These phenomena have also be…
Finite-system Multicriticality at the Superradiant Quantum Phase Transition
Han-Jie Zhu, Kai Xu, Guo-Feng Zhang +1
We demonstrate the existence of finite-system multicriticality in a qubit-boson model where biased qubits collectively coupled to a single-mode bosonic field. The interplay between…
Pentaquark components in low-lying baryon resonances
Kai Xu, Attaphon Kaewsnod, Zheng Zhao +4
We study pentaquark states of both light and hidden heavy (q = u,d,s quark in SU(3) flavor symmetry; Q = c, b quark) systems with a general group theory a…
