... but I think this means we're probably going to see room temperature quantum computing on integrated circuitry within the not-too-distant future. (For values of 5 years << NTDF << 20 years.)
So, what are the second-order implications[*] of being able to manufacture and deploy room temperature chips able to perform > 1 billion quantum operations per second on n >= 32 qubits per register and n >= 1 billion qubits of on-chip storage, for about the price of a present day high-end Intel server grade CPU? (i.e. US $100-1000 per unit and power consumption in the range 10-100W, suitable for embedding in commodity servers and high-end laptops?)
And thinking further, what are the implications of yadda for about the price of a present day ARM core (i.e. US $0.5 - $50 per unit, and power consumption in the range 10-500mW, suitable for embedding in cheap handheld devices like mobile phones)?
[*]Yes, yes, I know: public key crypto suddenly gets a lot harder. And we learn to live with much better, albeit non-deterministic, solutions to the travelling salesman problem and the blind knapsack packing problem, etc. And Roger Penrose has to come up with another argument to support his prejudice that consciousness is non-computable. What I want to know is, what else happens?
