Abstract :

Entanglement is a very important quantum resource in quantum communication, which guarantees the security of communication and has many important applications in quantum communication, such as quantum key distribution, quantum teleportation, and quantum dense coding. We demonstrated a theoretical entanglement state transmission scheme using time-bin operations. The scheme is robust against the instability of the reference frame between two parties, and can be extended to Greenberger-Horne-Zeilinger (GHZ) states without shared reference frame (SRF). When Pockels cells are used in the scheme, the success probability can be improved to 100%. The entanglement states are shared between many parties with no shared reference frame, which is significant for quantum communication and the construction of a long-distance communication networks.
