研究目的
To get the best average fidelity of quantum teleportation, which Bell states channels are less affected by the common collective noise environment.
研究成果
The Bell 1 state is always the best quantum channel to complete quantum teleportation protocol, especially in common collective Pauli σy noise environment, where perfect quantum teleportation can be achieved.
研究不足
The study focuses on collective noise environments and does not extensively cover individual noise environments. The practical implementation of choosing the best Bell state as a quantum channel in real-world scenarios may face challenges.
1：Experimental Design and Method Selection:
The study uses the standard quantum teleportation protocol and different noise models encountered in the real world to compute the average fidelity.
2：Sample Selection and Data Sources:
The quantum channel is assumed to be a maximally entangled pure state between Alice and Bob, affected by local collective noise environments.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned.
4：Experimental Procedures and Operational Workflow:
The evolution of an open quantum system is described by the Lindblad equation under the assumption of weak coupling and markovian approximation.
5：Data Analysis Methods:
The efficiency of standard quantum teleportation under noise is measured by calculating the fidelity and average fidelity.
