While noone has been able to build a Quantum Computer yet (at least not publicly), their creation may not be far off, and when they make their debut, they could snap the unbreakable steel spine of cryptography in two, solving problems that would take traditional processors many years in mere moments, rending all current cryptographic based currencies vulnerable.
But the same people on the forefront of quantum computation suggest an elegant solution to this problem. Quantum Cryptography. Encryption many times more complicated than we currently use, an enhanced iteration that would match these future super computers abilities and give them something they couldn't bite through in one chomp.
Today, we are seeing more and more applications utilizing GPGPU processing over the traditional CPU method of computation. I wonder, is this an indicator that we have reached the limits of the microprocessor?
Once that limit becomes more apparent and we hit the ceiling more often in consumer level applications, I think we will see the push for Quantum based computing accelerated.
