A bit can be either 0 or 1. A qubit can be a quantum superposition of |0> an |1>. The benefit of the latter is that as a qubit progresses through a computation the final answer will exhibit interference effects from the different routes it could take. Algorithms can be designed so that...
I believe the answer is that a quantum computer can be simulated by a classical computer with polynomial resources and exponential time. The time isn't infinite but still I wouldn't consider it to be reasonable (it could be the life time of universe if you pick the right problem to compare them...
Lets say you mark photons at the slits with either having vertical (|) or horizontal (-) polarization. On the screen it appears there is no interference, but there is. Think what happens when the phase between (|) and (-) is zero you get a diagonal polarization like this (/). If the phase is pi...
I understand why you might be frustrated with the answers your getting here. Although they are correct they aren't helping you understand why. I will make the suggestion that posting your question in the relevant forum section might help. This is the "quantum physics" section. It would have been...
Ok, assuming what you mean is which force transfers kinetic energy in a collision, the answer would be the electric force. The atoms in each object repel each other so rather than one object passing through another they "collide" due to electric repulsion between the electrons orbiting each...
your misinterpreting my meaning. My question is about where I can get the movie, I didn't specify anywhere it had to be from an illegal source. I'm asking for help finding it because I can't find it. If you can't find it either then fine.
