This prolongs the life of the satellite by reducing the level of "noise" that disables the quantum communication system.

Key Points: 
  • This prolongs the life of the satellite by reducing the level of "noise" that disables the quantum communication system.
  • The exchange of secret keys between users of a communication network enables a safe way to exchange messageswithout eavesdropping and information leakage.
  • However, a quantum computer is, basically, capable of breaking even such encryption due to the so-called Shor's factoring algorithm .
  • They make use of public optical channels to securely distribute keys by exchange of quantum bits, carried by single photons of light.
