【摘要】 |
|
Because the rates of quantum key distribution systems are too low, the interleaving technique and interpolation technique are used to extend the capacity of the quantum key warehouse to increase the quantum key rates of quantum secure communication systems. The simulation shows that the interleaving technique and interpolation technique can extend random sequences and that their randomness are invariable. The correlative theory and technique of digital signal processing is an effective method of extending the quantum key warehouse. |
