Neurons are not particularly good at multiplication. However...
Is 0.3 eV for a single switching event good enough for you?

Notice that a spintronics device is completely static; i.e. it consumes
no energy when it's not switching.

Would single-photon emitters and detectors be good enough for you?
In principle you can compute with about the same amount of energy
a single enzymatic reaction takes. Plenty of room at the bottom,

Of course. Just don't use our current computers for a yardstick.
