Years ago I created four molecular processors -- my kids.
A friend went to Comdex (or somesuch) about 10 years ago and told me he saw something like this at the IBM booth. Laser mounted on an arm and pointed at a 1 inch cube of quartz. They told him he was looking at 3 terabytes of memory, using the spin of the atoms to represent 1's and 0's. Maybe this announcement means they are close to production.
