A Quantum computer works not on the same basics of a Turing machine, so even those 8 bits are faster than you think. Quantum computers work because they routinely calculate infinite possibilities to arrive at a solution. *That's* why it's so fast. The reason it can handle infinitely large amounts of numbers is because the photon that hits the atom, turning it so that it represents a 1 or 0 in a normal computer, bounces off with an infinite number of possible directions, meaning the atom has an infinite number of possible orienatations. The possible states of an array are about 2 followed by 1,000 zeroes, or larger than the number of atoms in the known universe.
