Quantum Computing Compact

What is the phenomenon of quantum entanglement? If you read popular science literature, there is talk of socks that are red and blue at the same time, but monochromatic - how is that supposed to work? If you read scientific literature, you have to have knowledge of functional analysis.This book vividly builds the bridge between the experiments that led to quantum entanglement and the algorithm for teleportation, assuming only an elementary knowledge of mathematics.
