So we know that tunneling happens.

Tunneling is not more strange than the rest or unexplained than the rest of quantum physics.

So if you can get a good picture of the world that comes with quantum physics, you get tunneling for free.

It does kind of sound like that.

Yeah, so I'm going to take the second part first.

I don't think that anyone who works seriously in that field thinks that quantum computers will ultimately replace all computers.

I don't even think that they're going to replace all supercomputers.

There are things that...

classical, normal computers can do better than quantum computers and vice versa.

And I don't think that that's going to change.

Also, let's explain what a quantum computer is.

A quantum computer is a computer that harnesses some of the strange and... No, that's not a good way of saying it, right?

Because the usual way that people say it is, oh, a quantum computer is a computer that runs in quantum physics.

Everything runs on quantum physics, so all computers run on quantum physics.

Then people say, oh, quantum computer is a computer that uses special properties of quantum physics to do certain computational tricks.

That's not specific enough either because semiconductors, which are what, like the computer in your lap,

And in my pocket, like all computers are built on basically.

Semiconducting itself is a quantum property.

Like you can explain, you can't explain that without quantum physics.

A better definition of a quantum computer is a computer that uses specific quantum properties like superposition and entanglement to perform certain computations that normal conventional computers cannot perform as quickly in that way.
