研究目的
To propose a one-step quantum key distribution protocol based on hyperentangled Bell state that does not require storing quantum states and is secure against intercept-measure-resend and entanglement-measure attacks.
研究成果
The proposed HQKD protocol does not require storing quantum states and is secure against intercept-measure-resend and entanglement-measure attacks, with a high eavesdropping detection efficiency. However, technical challenges in fabricating and measuring hyperentangled Bell states and single particles remain.
研究不足
The protocol requires the fabrication and measurement of hyperentangled Bell states and single particles, which may be challenging with current technology. Additionally, mixing hyperentangled Bell states and single particles presents technical difficulties.
1：Experimental Design and Method Selection:
The protocol involves encoding every 6 classical bits into a group using a hyperentangled Bell state and a single particle, transmitting them to the receiver who measures the hyperentangled Bell state's position to detect eavesdropping.
2：Sample Selection and Data Sources:
The protocol uses hyperentangled Bell states and single particles for encoding and transmitting information.
3：List of Experimental Equipment and Materials:
Not explicitly mentioned in the paper.
4：Experimental Procedures and Operational Workflow:
The sender divides the information into groups, encodes them, and sends them to the receiver who measures and compares results to detect eavesdropping.
5：Data Analysis Methods:
Security analysis under intercept-measure-resend and entanglement-measure attacks is performed to evaluate the protocol's security.
