Hi, I'm going through Nielsen and Chuang's Quantum Computation and Quantum Information textbook and I don't really understand this part about quantum parallelism: Shouldn't the resulting state be (1/sqrt(2^4)) * (|0, f(0)> + |0, f(1)> + |1, f(1)> + |1, f(0)>), since the resulting state would...

Okay, thank you! I think I understand this better. But I'm still confused why Griffith's says E = δ/ε0n_hat immediately outside a conductor... Wouldn't this only apply for conductors that are infinite planes?

Griffith's says this, and I'm not exactly sure why... If you had a solid, spherical, and externally induced conductor... Does this mean that IMMEDIATELY outside, when you're infinitesimally close to the surface, E looks like this? If you surround the entire conductor with a Gaussian surface...

Hi there! I'm currently a senior in high school and about-to-be undergrad student! Short term, I hope to major in astronomy and physics; long term, I hope to pursue graduate studies in the same field and head into academia. See you around!

Hello there! I recently had the privilege of being accepted to UC Berkeley and Cornell for my undergrad! I'm very grateful to both universities for this opportunity. I'm just generally wondering what factors for grad school admission I should be considering when choosing between unis, like...
