In a research paper published in Nature Physics , an international research team led by the University of Pennsylvania , in collaboration with the University of the Witwatersrand , Nanyang Technological University (NTU) , and South China University of Technology , has demonstrated the preparation and reconfigurable transfer of photonic quantum skyrmions on an integrated nanophotonic chip.
By leveraging spin-orbit-locked microring resonators on a silicon nitride (Si 3 N 4 ) platform, the researchers succeeded in transferring topological skyrmion structures from single photons to two-photon entangled states, establishing a noise-resilient quantum state transfer mechanism that maintains its topological invariant even after entanglement vanishes.
