FYI: 3 qubits encrypted

Apparently, it is as hard (or harder) to produce random qubits as random
bits. There are some sentences in this article that don't make sense so
I am guessing the author doesn't really understand the subject.



  ...random operators would be useful for quantum 
  communications tasks like encryption, said Emerson. 
  "The idea is to randomize a specific configuration of 
  qubits containing the message, and then transmit this 
  randomized state," he said...The researchers tested the 
  method on a three-qubit prototype liquid nuclear 
  magnetic resonance (NMR) quantum computer.
