First Commercial Quantum Computer

This past week, D-Wave Systems announced the sale of the first commercial quantum computer to Lockheed Martin.

Although quantum computers are still in their infancy (we're talking ENIAC-like infancy here), their potential is astounding.  The most interesting thing is that certain problems that are hard for conventional computers should be very easy for quantum computers.  This could have some really unexpected results, such as defeating almost all of the cryptographic techniques we normally use to protect our information today.

I don't know if what D-Wave has is the beginning of something significant or not.  However, for a mere $10M, you could buy one and find out.
