Friday Nov 19th Sections 19.1 and 19.2

  Today's reading was on quantum computing, The polaroid filter thing is really cool, I have see that in my physics classes before, and every time I go to get new glasses I play with the polarized sunglasses doing the same thing.
  Using the quantum effects of measuring photons to test to see if someone was evesdropping blows my mind, such a cool idea.  I am taking physics 222 right now and the class is basically all quantum mechanics, excepting the first three weeks on general relativity.  I am still not sure how there is a probabilistic algorithm that factors integers.  But I think it might have to do with solving the central potential spherical shrodinger equation.  The answers to those solutions are integers, and there might be a way to perturb the system so that there is a relation between the two perturbation states?  A relation that has to do with primes?  Well, the next section might answer that so I am going to go read that instead.
