I understood many maths of QM and even QFT.. but I can't totally understand how a quantum computer can factorize millions of times faster. In normal turing machine, there is 0 and 1. But in quantum computers, there is 0 and 1 and superpositions of it.. meaning it can be 0.0001 or 0.5253 or 0.874 or anything in between.. meaning billions of combinations in superposition, is this right? But we know that when we measure, there is only one value, so how do they use it to compute? it's something about entangling it with another particle. I have visited dozens of websites about quantum computer, it's not yet clear how it works. Anyone can point me to a good site with very clear explanation or produce some rough ideas yourself. Thanks.
