Quantum key distribution with a control key
2017 International Symposium on Wireless Communication Systems (ISWCS), 2017Quantum key distribution (QKD) relies on randomness to exchange secret keys among the communicating parties. While ensuring the secrecy of the keys being distributed, independent randomness also causes to reduce the number of key bits that can be shared per quantum signal exchanged.
