Quantum, not binary. You should be of 3+ minds, with 4 minds being what engineers are trying for right now.

Is the answer "it doesn't matter unless we actually have one?"

Yes, maybe, and no.

We have them. People have built quantum computers that can factor 15 digit numbers, which is a big deal for cryptography. What we don't have is a quantum computer with enough entangled qubits that it's anywhere near what a classical computer can do outside of very special-purpose computations.

Maybe it already has and we just don't know it....

Well, if it can't power my cell phone and show me teh bewbies faster, it's useless to me.

// why can't quantum computing be more like his sexy older brother, the doctor's iPad?

A Huge revolution is going to happen at an incredibly Small scale.

Canada is lucky to have the front seat to this new age.

So we don't.

It sounds trippy, but the idea that our reality is just a simulation run by a "higher order" universe would not only explain the quantum uncertainty principle, but render it an inherent characteristic of our universe, rather than merely a limitation of our ability to observe it.

Does anything simulate reality now?

If you ignore the quantum computers that we have, then no, we don't have any quantum computers.

The only commercial solution I know of is the D-Wave system, typically regarded as "a pile of junk" by many scientists.

The reason being that it performs a single mathematical function and that's it. Oh and it is around $20 Million.
