I did quantum theory at University for 3 years and I loved it but understood about 10% of it. So move along now, nothing to see here.
One of my inventions, ahem, in the ‘definitely needs work’ category, was the Heisenberg resonator. Quantum computing is hard because keeping states from collapsing for any length of time is hard. The Heisenberg resonator is a device that quite deliberately observes the quantum state forcing it to collapse, but does so at a regular frequency, clocking it like a chip in a PC. By controlling the collapse, the idea is that it can be reseeded or re-established as it was prior to collapse in such a way that the uncertainty is preserved. Then the computation can continue longer.
You can build on this nicely, especially if you believe in parallel universe interpretations, like my friend Richard Yonck might do, in whose honour this next invention is sometimes named. Suppose we can use quantum entanglement to link particles together, but only loosely. They are tangled in one universe and not in another. Circuits for computation in any universe could be set up using switches in a large array that are activated by various events that are subject to quantum uncertainty and may only happen in some universes. Unlike a regular quantum computer that uses qubits, this computer would have uncertain circuitry too, a large pool of components, some of which may be qubits, which may or may not be connected in any way at all. Sometimes they are, sometimes they aren’t, sometimes they might be and sometimes across universes. Ideally therefore, it would replicate an almost infinite number of possible computers simultaneously. Since those computers comprise pretty much the whole possible computer space, a Yonck computer would be able to undertake any task in hardware, instantly. Then the fun starts. One of the potential tasks it might address is to use trial and error and evolutionary algorithms to build a library of circuitry for machine consciousness. It would effectively bootstrap itself. So a Yonck computer could be conscious and supersmart and could spring into existence just by designing it. In one universe you may have bothered to build the damned thing and that is enough to make it work. It would figure out how to span the gulf and spawn into all the rest.
Well, I’d buy one. Happy Christmas Richard!
