There are a few startups making analog ML compute. Mythic & Aspinity for example https://www.eetimes.com/aspinity-puts-neural-networks-back-to-analog/ https://

How is that doing quantum logical computations with electron charge different from from what e.g. Cirq or Tequila do (optionally with simulated noise to simulate the Quantum Computer Engineering hardware)? FWIU, analog and digital component qualities are not within sufficient tolerance to do precise analog computation? (Though that's probably debatable for certain applications at least, but not for general purpose computing architectures?) That is, while you can build adders out of voltage potentials quantified more specifically than 0 or 1, you might shouldn't without sufficient component spec tolerances because noise and thus error. IMHO, Turing Tumble and Spintronics are neat analog computer games. (Are Qubits, by Church-Turing-Deutsch, sufficient to; 1) simuluate arbitrary quantum physical systems; or 2) run quantum logical simulations as circuits with low error due to high coherence? https://en.wikipedia.org/wiki/Church%E2%80%93Turing%E2%80%93Deutsch_principle https://en.wikipedia.org/wiki/Church%E2%80%93Turing%E2%80%93... ) >> See also: "Quantum logic gate" https://en.wikipedia.org/wiki/Quantum_logic_gate https://en.wikipedia.org/wiki/Quantum_logic_gate Analog computers > Electronic analog computers aren't Electronic digital computers: https://en.wikipedia.org/wiki/Analog_computer#Electronic_analog_computers_2 https://en.wikipedia.org/wiki/Analog_computer#Electronic_ana...

  Analog pid controllers: https://www.youtube.com/watch?v=Ps9iD738rUg https://www.youtube.com/watch?v=Ps9iD738rUg Soviet IR tracking missile heads too. Stumbled upon one on ebay once, was surprised the control system was analog. Not sure which one it was and I'm very surprised to find a Raytheon AIM 9 Sidewinder missile kit there: https://www.ebay.com/itm/273992271867 https://www.ebay.com/itm/273992271867
