1630s, from French computer, from Latin computare “to count, sum up, reckon together,” from com- “with” (see com-) + putare “to reckon,” originally “to prune" (see pave). Related: Computed; computing.
early 14c., “to cover (a street) with stones or other material,”…
This quantum computer then, adds 2 + 2 and 3+1 at the same time. It does this and that at once.
Quantum computer have this intrinsic multitasking ability, that ordinary computers don’t, why? Because the bits are quantum mechanical, and because these quantum bits, for reasons nobody understands, can be zero and one at the same time, just as electrons can be here and there at the same time.
As as a result quantum computers can do two things at once, or 4 things at once, or 8 things at once, or 1,000,000,000 things at once or 2X10high300.
And I pick 2X10high300 because that’s equal to the number of particles in the universe.
So a quantum computer with 300 bits can do as many things as there are particles in the universe."
