The Computational Power of a Quantum Computer

The goal of making more and more powerful quantum computers is basically overcoming Decoherence. We're really trying to harness quantum coherence and creating as large of of these quantum coherent Cubits systems as we can. As you increase the number of bits you increase your computational power But it goes up linear so I go from 10 bits to 100 bits to a thousand bits and the computational power scales up equal To how many bits I have now.
