Entanglement concentration of high-dimensional unknown partially entangled state
Si-Qi Du, Guo-Zhu Song, Hai-Rui Wei
High-dimensional quantum systems offer a number of advantages in larger information capacity, stronger noise resiliency, higher improved efficiency and accuracy over the qubit syst…
Improved entanglement-based high-dimensional optical quantum computation with linear optics
Huan-Chao Gao, Guo-Zhu Song, Hai-Rui Wei
Quantum gates are the essential block for quantum computer. High-dimensional quantum gates exhibit remarkable advantages over their two-dimensional counterparts for some quantum in…
Synthesis and upper bound of Schmidt rank of the bipartite controlled-unitary gates
Gui-Long Jiang, Hai-Rui Wei, Guo-Zhu Song +1
Quantum circuit model is the most popular paradigm for implementing complex quantum computation. Based on Cartan decomposition, we show that generalized controlled- (GC…
Optical properties of a waveguide-mediated chain of randomly positioned atoms
Guo-Zhu Song, Jin-Liang Guo, Wei Nie +2
We theoretically study the optical properties of an ensemble of two-level atoms coupled to a one-dimensional waveguide. In our model, the atoms are randomly located in the lattice…
Microwave transmission through an artificial atomic chain coupled to a superconducting photonic crystal
Guo-Zhu Song, Leong-Chuan Kwek, Fu-Guo Deng +1
Emitters strongly coupled to a photonic crystal provide a powerful platform for realizing novel quantum light-matter interactions. Here we study the optical properties of a three-l…
Photon transport mediated by an atomic chain trapped along a photonic crystal waveguide
Guo-Zhu Song, Ewan Munro, Wei Nie +3
We theoretically investigate the transport properties of a weak coherent input field scattered by an ensemble of -type atoms coupled to a one-dimensional photonic crystal wavegu…
