I think Quantum Computers don't and never will exist. Quantum mechanics is religious psuedo scientism.
However researching new computer hardware components may help with faster computer especially when using light in processing.
Also, NuBits peg broke I remember telling you guys on slack it would go back to a dollar on speculation alone. Was an easy way to double BTC. Unfortunately the volume was so low you couldn't buy in enough to make significant amounts.
Well since I'm not the most tech saavy guy out there, the whole concept does seem like a 'pipe dream'. So yeah I agree, yet adding Moore's law to the equation, any new innovation is in high demand.
Didn't know about light speed processing. Thanks. Found this link on it
