Quantum computing could head to 'the cloud', study says

@wuliheron

Electronics work by the electrical charge of the electron, spintronics use the spin instead. Its much faster and more efficient, but requires extreme precision engineering that hasn't been well developed yet. Plasmonics are a type of pseudo-optics, a kind of optical-electronic hybrid waveform, that have much shorter wavelengths then regular optics and are being developed for optical computing on chips because of their small size. Both optics and spintronics can at least theoretically be used for classical computing at close to the speed of light or even quantum computing.

Interesting

In a classical computer its impossible, but not for a quantum computer where collectively the entangled particles can represent the factorial of their number. In the case of quantum entanglement there is strength in numbers and the total is greater then the sum of its parts.

So 128 atoms could represent 3.85620482 x 10^215 atoms? How much mass would 3.85620482x10^215 atoms of carbon come out to?

Like I've said in previous posts, it can be used to do all sorts of calculations that can't be done on a conventional computer. They could be useful for anything from quantum research to mathematics to medicine to designing the next compact car.

Or creating something like a simulated universe a'la The Matrix...

Its 128 particles which are much smaller then an atom. For scale if an atom were the size of a 14 story building its electrons would be like dust particles and its entire nucleus would be about the size of a grain of salt. If photons are used they have no rest mass whatsoever and electrons have a very tiny mass even by particle standards.

Knowing my luck it would all be designed by Disney Studios.

So they're using electrons?

I don't understand what you mean...

How much is '500 atoms worth' of data exactly?

How much is 1 atom worth of data?

1 atom worth of data can be a LOT of data, in theory. Certainly more than the amount of data that can actually be held by the atom itself. This is because the data is contextual. It all depends on where the atom is and what it is doing when you look at it.

It's a figure of speech

Again, its not "an" electron. Its many entangled electrons or photons or whatever and quanta are contextual. An ordinary silicon chip, for example is composed of a very small hand full of sand, yet it can be used to calculate something as large as the size of the universe. How? Because the whole is greater then the sum of its parts.
