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…
