Diamonds are forever secure

The basis of secure communication is generating a random number, known as the key, that is shared by the recipient and the sender that is then used to scramble and unscramble the message that is sent between the two parties. The problem is that there is no way computers can generate truly random numbers, just complicated algorithms that are hard but not impossible to crack. The second problem is generating random numbers in enough large quantities that can be used for daily commerce.

A professor from Ottawa University, Ben Sussman, may have found a solution using diamonds and quantum mechanics. Geekosystem breathlessly explains how it all works:

The process works a little something like this. Sussman takes a big old beam of science a laser, and fires a several-trillosecond burst through a diamond. In the process of going through the diamond, the laser fundamentally changes in completely random ways
