Hypothesis
Can trusting other users in a quantum network increase the key rate?
Conclusion
Trusting other users in a quantum network allows for higher key rates by retaining correlated keys.
Supporting Evidence
- The proposed network allows users to increase their key rate by trusting others.
- The total key rate of the network reaches 1 Mbps with an average distance of 11 km.
- An untrusted protocol achieves a key rate of only 0.4 Mbps.
Takeaway
If you trust your friends in a special network, you can keep more secret codes instead of throwing them away.
Methodology
The study proposed a continuous-variable quantum passive optical network where users can trust each other to increase key rates.
