General discussions about "science" itself
Be sure to also check out these other Fediverse science communities:
"The fact that triplet superconductors have spin has an important consequence. We can now transport not only electrical currents but also spin currents with absolutely zero resistance," explained Linder.
That ability could make it possible to transmit information using spin without any energy loss. In turn, extremely fast computers could operate using almost no electricity at all.
I don't know what any of this means... but cool!
Still need massive amounts of energy to cool them down to superconducting temperatures
Well, if we had these aboard the International Space Station or a spaceship, we could simply choose to crank the heat down in the computer room. Might actually save energy in that case.
Dream big!
It is very hard to cool things down in space
How about in a crater on a Moon pole?
NbRe? Why not a computer made of rhino horn ivory?
So...does this mean it will soon be able to multiply two-digit numbers?
It would be a terrible machine for that. Never use a quantum computer to multiply numbers.
Isn't that kind of a thing it needs to do to find the factorials of large numbers to break traditional encryption?
Not really. It needs to apply unitary operators to elements in Hilbert space, which is essentially multiplying matrices onto vectors.
Which you could do by multiplying the involved numbers one by one, as most classical methods would, but then you're missing the point of using a quantum computer.
just in time for all the bad press it got last week!
