1. I don't quite understand how basis of vector spaces work into quantum computing. Hence, the quantum key distribution did not make much sense. Basis of vector spaces wasn't my strong point of linear algebra as well. I also have difficulty understanding how the quantum key distribution is any different from the digital computing of now; it just seem like they were using different symbols for 0 and 1.
2. This whole topic is interesting; the possibilities that are out there if quantum computing does work out. I found it interesting, from the quantum key distribution that if Eve listens in, it changes the data sent or the state of the photon. This seems that it quantum computing may offer new security as well as the power to destroy security. It would be a whole new ball game.
