Practically Enhanced Hyperentanglement Concentration for Polarization-spatial Hyperentangled Bell States with Linear Optics and Common Single-photon Detectors
Gui-Long Jiang, Wen-Qiang Liu, Hai-Rui Wei
Hyperentanglement, defined as the simultaneous entanglement in several independent degrees of freedom (DOFs) of a quantum system, is a fascinating resource in quantum information p…
Heralded and high-efficient entanglement concentrations based on linear optics assisted by time-delay degree of freedom
Gui-Long Jiang, Wen-Qiang Liu, Hai-Rui Wei
Entanglement concentration is a critical technique to prevent degraded fidelity and security in long-distance quantum communication. We propose novel practical entanglement concent…
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…
Linear optical universal quantum gates with higher success probabilities
Wen-Qiang Liu, Hai-Rui Wei
Universal quantum gates lie at the heart of designing quantum computer. We construct two compact quantum circuits to implement post-selected controlled-phase-flip (CPF) gate and To…
Deterministic and complete hyperentangled Bell states analysis assisted by frequency and time interval degrees of freedom
Xin-Jie Zhou, Wen-Qiang Liu, Hai-Rui Wei +2
Hyperentangled Bell states analysis (HBSA) is an essential building block for certain hyper-parallel quantum information processing. We propose a complete and deterministic HBSA sc…
Collective unitary evolution with linear optics by Cartan decomposition
Wen-Qiang Liu, Xin-Jie Zhou, Hai-Rui Wei
Unitary operation is an essential step for quantum information processing. We first propose an iterative procedure for decomposing a general unitary operation without resorting to…
