in the memory location. It would slow the machine way down if you had to pump the bits to be operated on from the memory to the processor and back and forth through wires. Since the CPUs can only use a few kilobits per register it would be like filling up a five-gallon bucket with a cup. It would just take too long." I laughed that he just used the same analogy that I had used for my final exam and told him as much.
"Let me get this straight," I said. "The bottleneck here is actually being able to manipulate a lot of data in parallel. One CPU can't work on a terabyte of data all at once. Is that the problem?" I was beginning to understand why this was too good to be true.
Larry was smiling again. "You catch on quick, Stevie. Yep, that's the problem in a nutshell. If all we had to do was move data around this would be awesome fast. But we might want to add or multiply or something to that data sometimes. We need to be able to work on all the data at once in parallel."
We continued to bat around these ideas for a couple hours, occasionally taking bathroom and soda or coffee breaks. We finally finished up around five-thirty or so and decided to give it a rest. We packed up the classified room and put the disk back in the safe. Larry showed me how to get in and out of the safe. Then I grabbed my stuff from my desk. I had paperwork for my new pay grade and new insurance and benefits packages. I also took home a handful of technical journal papers that Larry gave me on EPR. One paper particularly caught my eye. It was entitled "Experimental Detection of Entanglement with Polarized Photons" and had been written by a bunch of Italian people. I planned to read it later that evening after walking Lazarus.
That day was a lot to absorb. I wasn't quite sure why the effort was Top Secret but it was. When I had asked about that, Larry just shrugged and told me that I didn't have a need to know that yet. But he did tell me that my job was to make the technology useful. Cool job, I thought. I could be instrumental in the development of the fastest, most powerful computer ever built. Wow!
Then my stomach growled and I remembered that the fridge at home was empty. So, I stopped and grabbed some burgers for Laz and me on the way home. Laz, as always, was happy to see me. I set the burgers on the counter and patted him on the head. Then I debated on a beer or a pill. I went with the beer. The next thing I knew it was seven-forty-six and Laz was licking me on the face and my beer was still in my hand.
"Damn, I must've dozed off. I guess I should take those pills a little more regularly, huh buddy." I scratched his white belly and he whined at me and kicked his hind legs like dogs do.
I got up and heated us up a couple hamburgers. We ate dinner and then went for a walk, happier than I had felt in a long while.
CHAPTER 6
A couple of months passed before I made any headway at all on the Quantum Connected CPUs. I spent weeks on the Framework, in chat rooms, newsgroups, and downloading books on quantum mechanics, statistics, EPR experiments, Bell's Inequality, Schroedinger's Cat, and the effects of measurements on quantum phenomena. It turns out that although people had been trying to do quantum teleportation and such in experiments, nobody had really put it together with computing. It seemed kind of obvious to me once I was educated on the subject. Larry told me that that is "typical of classified projects." After all, isn't it pretty damned obvious that if you don't want the surface of your aircraft to reflect radar back at the radar then you should minimize the surface area that the radar aperture sees? Maybe it wasn't, since the stealth technologies were unheard of for years. But, now that the cat is out of the bag, it's useless. Larry also had told me something that Heinlein, this science fiction author that I had never heard of, had written. Heinlein had once said something like "a secret weapon must be just that, a secret." It makes
