One quantum computer in the future will have the combined processing power of all computers on earth today.
Indeed, the potential processing power of quantum computers truly boggles the mind. Because a quantum computer essentially operates as a massive parallel processing machine, it can work on millions of calculations simultaneously (whereas a traditional computer works on one calculation at a time, in sequence).

*sigh
Based on Moore's law, computing will reach it's zenith in twenty forty-nine. Problem is we don't have the raw materials to conduct such processing power. Quantum computing is nice but we will have to go MUCH farther before we have self replicating, civilization creating monoliths LOLS
fyi We live in supercomputer, but you didn't hear that from me.
