Geometric entangling gates for coupled cavity system in decoherence-free subspaces
Yue-Yue Chen, Xun-Li Feng, C. H. Oh
We propose a scheme to implement geometric entangling gates for two logical qubits in a coupled cavity system in decoherence-free subspaces. Each logical qubit is encoded with two…
Quantum phase transition of two-mode Bose-Einstein condensates with an entanglement order parameter
Wei Fan, Yan Xu. Bing Chen, Zhaoyang Chen +2
The ground state entanglement of the two-mode Bose-Einstein condensate is investigated through a quantum phase transition approach. The entanglement measure is taken as the order p…
Strongly interacting and highly entangled photons in asymmetric quantum well with resonant tunneling
Shuangli Fan, Hui Sun, Xun-Li Feng +4
We propose an asymmetric quantum well structure to realize strong interaction between two slow optical pulses. The linear optical properties and nonlinear optical responses associa…
Probing Half-odd Topological Number with Cold Atoms in a Non-Abelian Optical Lattice
Feng Mei, Shi-Liang Zhu, Xun-Li Feng +2
We propose an experimental scheme to probe the contribution of a single Dirac cone to the Hall conductivity as half-odd topological number sequence. In our scheme, the quantum anom…
The scalable quantum computation based on quantum dot systems
Jian-Qi Zhang, Ya-Fei Yu, Xun-Li Feng +1
We propose a scheme for realizing the scalable quantum computation based on nonidentical quantum dots trapped in a single-mode waveguide. In this system, the quantum dots simultane…
Quantum controlled phase gate based on two nonresonant quantum dots trapped in two coupled photonic crystal cavities
Jian-Qi Zhang, Ya-Fei Yu, Xun-Li Feng +1
We propose a scheme for realizing two-qubit quantum phase gates with two nonidentical quantum dots trapped in two coupled photonic crystal cavities and driven by classical laser fi…
