AbstractThe robust operation of quantum entanglement states is crucial for applications in quantum information, computing, and communications1,2,3. However, it has always been a great challenge to complete such a task because of decoherence and disorder. Here, we propose theoretically and demonstrate experimentally an effective scheme to realize robust operation of quantum entanglement states by designing quadruple degeneracy exceptional points.

Graphical Abstract Robust Generation of Entanglement States An entangled state generation insensitive to the incident state is realized around exceptional lines based on a quantum walk platform. The evolution around exceptional lines is independent of the initial state and evolution direction, and more efficient than other protocols.
