No, it's still 'binary', after a fashion.
But rather than definite 0 and 1 states, you have superpositions of states, such as "mainly 0 but slightly 1" (sort of).
You still have just two choices, but you don't have to make the choice until you want the final answer.

Not true. Quantum computers have more than two states. It's not simply ON-OFF-and everything in between.
They're three opposing states, like three perpendicular lines on a 3D axis. Rock, paper, scissors. Larry, Curly, Moe.

But more to the point:
they're many many many years away from becoming a workable reality, and even if (when) they do become reality some cunts will just try and massacre people with them.

Well, some might have,
but the ones I read about used 'qubits', i.e. quantim bits, i.e. quantum binary digits.

You could have 'trinary' arithmetic with a perfectly classical computer, it'd just be a lot more complicated to construct than a traditional binary computer.

Absolutely. Quantum computers will make it practical.
Practicality is necessary for grand-scale application of a technology.

I think much of it has to do with the way people are taught. We live on (apparently) flat ground. For thousands of years we believe in opposites. The sky and the ground, heaven and hell, yes and no.

Hmmm, weeelll, maybe.
I remain sceptical. Quantum computing works fine as a mathematical toy, but is a LONG way from being proven even as a physical possibility.

And as for things being teleported across regions of space, nothing short of a method of manipulating space-time will allow that, quantum computers or not.

Having reached a neutral point, I declare this a good conversation.
Thanks, I feel refreshed now.

I rerached a wonderful conclusion in my subject
The art of eating burgers. So I am contented.

This theory,
of course, only applies to burgers with either not much salad filling, or a large bap to salad ratio.

the earth is not flat
I can prove it.

If you look out of my window you can see a hill. I know it's not an illusion, I tried climbing it at Easter.
