(a) Alice randomly generates a large number of three-photon GHZ states; (b) Alice distributes the GHZ state to Bob1 and Bob2; (c) the first round of security checking; (d) the identity authentication; (e) Alice releases the entanglement; (f) Bob1 and Bob2 encode messages; (g) ...
This study proposes a measurement property of graph states and applies it to design a mediated multiparty quantum key distribution (M-MQKD) protocol for a repeater-based quantum network in a restricted quantum environment. The protocol enables remote classical users, ...
Quantum graph states, as a kind of quantum states that describe the complex entanglement relationship of multi-body quantum systems, have advantages such as scalability, measurement friendliness, and error tolerance, provide a stronger security than the methods based on the quantum mechanics itself by...
