Comment Re:256 qbit per atom? (Score 1) 135

Not exactly. They have quite some clever ways to handle these Rydberg states in neutral atoms. They use hyperfine splitting to get a large amount of qbits in single atoms.

Comment I don't really see the problems in wind/solar powe (Score 1) 835

In wind power, yes, you use rare earth materials. But at end of life, these can be recycled. It's not like we throw
the rare earth materials into space when we're done with them.

Solar power uses ground water in deserts. Does this even run out? I mean, ground water is there because it rains or comes in from the sea.
Evaporating water from solar panels still make it into rain and so the cycle should continue.

What's the fuss?

Comment Plasticity (Score 1) 220

I wonder if this chip can do plasticity and learning just as a real brain.

One thing is to hardwire a neural network, another is to mimic the brain.
The brain constantly rewires itself in different ways to learn.
