How does a quantum computer work

2) The probabilities of quantum bits are calculated using complex numbers. The math behind quantum probability uses complex numbers (imaginary numbers). This means the spinning quarters analogy I gave you is overly simplistic. You would need to use vector math to calculate probabilities instead (which is much harder).
