Decoherences-protected implementation of quantum gates
Chunfeng Wu, Chunfang Sun, Jing-Ling Chen +1
We present a scheme to implement a universal set of quantum gates based on achievable interactions, and the gates can be protected against decoherences through dynamical-decoupling…
Greenberger-Horne-Zeilinger States: Their Identifications and Robust Violations
Xing-Yan Fan, Jie Zhou, Hui-Xian Meng +3
The -qubit Greenberger-Horne-Zeilinger (GHZ) states are the maximally entangled states of qubits, which have had many important applications in quantum information processin…
Implementation of hybridly protected quantum gates
Chunfeng Wu, Chunfang Sun, Gangcheng Wang +2
We explore the implementation of hybridly protected quantum operations combining the merits of holonomy, dynamical decoupling approach and dephasing-free feature based on a simple…
Multi-qubit Quantum Rabi Model and Multi-partite Entangled States in a Circuit QED System
Jialun Li, Gangcheng Wang, Ruoqi Xiao +3
Multi-qubit quantum Rabi model, which is a fundamental model describing light-matter interaction, plays an important role in various physical systems. In this paper, we propose a t…
Conditional displacement interaction in ultrastrong-coupling regime
Gangcheng Wang, Qingyong Wang, Yimin Wang +3
We investigate the realization of conditional displacement interaction in the transversal direction in ultrastrongly coupled circuit quantum electrodynamics by adjusting parameters…
Generalized James' effective Hamiltonian method
Wenjun Shao, Chunfeng Wu, Xun-Li Feng
James' effective Hamiltonian method has been extensively adopted to investigate largely detuned interacting quantum systems. This method is just corresponding to the second-order p…
