    • Comment on the implementation challenges.
    • Summarize the main advantages of quantum computing.
  2. Topic 2
    • Summarize the main advantages over classical encryption: how does quantum mechanics help?
    • Describe the basic q. cryptography operating protocol.
  3. Topic 3
    • Explain as best you can the phenomenon of entanglement.
