Scientists at the CAS Key Laboratory of Quantum Information have designed a beam splitter which allowed to generate a two-photon Qbit hyper-entangled state with high fidelity. The experimental results show that single-particle contextuality and two-party nonlocality can coexist, essential for device-independent secure communication and for fault-tolerant universal quantum computation.
