'Quantum effects' are already exploited in analog components. TFET's work by modulating quantum tunneling. Zener reverse breakdown in Zener diode is also quantum effect. Esaki diode uses quantum effects.
Unfortunately just because the single component relies on quantum effects does not have anything to do with quantum speedup in computation.
Quantum computation exploits entanglement in larger scale than normal. The whole computational state must be entangled quantum state. Separated quantum effects result just classical computer. The quantum circuit must be carefully arranged so that the interference pattern yields the result you want.
- sriku 7y agoWell, trivially that's a yes. However, the "specification level breach" property of A.T.'s work is what intrigued me - i.e. the circuits are specified to do a digital task, but work in an analog manner - constructing antennas and receivers - to the extent that the same digital circuit wouldn't work when written to another FPGA. Also, entanglement doesn't need to be perfect. You can have 1% entanglement too and have that propagate over time and operations. The question is whether an evolved circuit can figure out pathways to use that little bit of entanglement in ways that our understanding doesn't quite admit .. in much the same way as a digital FPGA designer wouldn't think about using not-gates as antennae. An unreliable circuit achieved this way would also be interesting I think.
