content: The quantum computer has these problems  It only certain problems, it is not a magical general purpose computer Getting the answer is easy, but converting this answer to "normal" space answer takes at least the same effort as a conventional computer. When you understand what the maths mean, then come to the conclusion that it never gives a correct answer. The answer it gives has a probability that it is correct. 1+3= 98% probably that it will be 4, but it also have a 1% probability that it is 3 or 5. When you understand this superposition claims then it is basically painting a dot on 5 ping pong ball and read the orientation of each ping-pong ball when you kick the box. Just like tarot reading.  However, the cool thing about this is new science could evolve from it, new materials and better understanding of quantum mechanics, but a miracle computer? It is most likely a big giant money scam.
