Recent developments in quantum computing motivate investigations of the ultimate limits to computation. By combining results in cosmic dynamics with entropy bounds it is possible to present limits to the amount of information and its processing rate in the universe up to the present. We find that both the total number of bits and number of operations for the universe does not exceed O(10123). Possible extensions of the information bounds are discussed, as is the nature of the holographic entropy bound.
