主 题：Photonic chip Quantum entanglement Topological photonics
摘 要：Quantum entanglement,as the strictly non-classical phenomenon,is the kernel of quantum computing and quantum simulation,and has been widely applied ranging from fundamental tests of quantum physics to quantum information ***,the topolog-ical phase is found inherently capable of protecting physical fields from unavoidable fabrication-induced disorder,which inspires the po-tential application of topological protection to quantum ***,we present the experimental demonstration of topologically protected quantum entangled states on a photonic *** process tomogra-phy shows that quantum entanglement can be well preserved by the topological states even when the chip material introduces disorder and relative polarization rotation in phase *** work links the fields of materials,topological science and quantum physics,opening the door to wide applications of topological enhancement in quantum regime.
