Quantum computing will have to address the following problems, 1) Algorithm of a finite gate quantum circuit, which will ensure 2)Self error correction, ensuring 'determinism' and Turing's 'halting problem'.
Sounds like such a thing would be very good for ultrafast digital signal processing. I wonder how precisely placed colour centers could be generated? I'm thinking it would either have to be done with a tightly focused electron beam or with ion implantation.
I think we will be able to merge Light or Photonic cpus to merge a cpu with a human brain! Thoughts must be some type of light anyway! The key would be finding the input point on the brain to insert the light cpu! I think the brain will learn how to read and pass thoughts in time!
