With a quantum computer, a bit is a 1 and 0 at the same time. So instead of calculating X or Y, a QC can calculate X and Y at the same time.
I think that's more of a disadvantage than an advantage. It's why quantum computers are very "noisy" compared to electronic computers, and why they don't (yet) lend themselves to digital problems like code-breaking.
Their advantage is pretty simple: quantum particles are smaller, cheaper, faster, etc. than electrons.

Goodbye every current encryption algorithm on the planet if true.

I see the potential in other areas but if everyone has QC doesn’t it make online security even more vulnerable?
Current data encryptions will be basically useless since a quantum computer could brute force it very quickly. However, it opens the door to quantum key distribution which will be many times more secure than what we have now.

So google will sell this to China?
It will be made in China and sit in a datacenter with the cheapest electricity.

That to me is the real risk/downside.
China is supposedly investing heavily in this arena, and I am sure they are spying heavily on notable projects like Google.
If China had access to an advanced quantum computer in the next five years and wanted to use it for ill, couldn't they hack the ten biggest banks in the US and cause financial catastrophe?
Supposedly there are encryption algorithms that are still somewhat safe against quantum computing, but I don't think there is anything that is well developed at this point.

That is what I got out of this article. Just the medical advances alone will be incredible.

Huge if true. Quantum computing will change the world

You should care. If the government gains the ability to break encryption, then what little privacy you have left is completely gone. The surveillance state will be complete at that point.

Yeah, I don’t even know what I’m looking at in that pic. Looks like a gaudy chandelier, not the Chromebook I was expecting.

So is QC the 21st century version of the arms race?

Yes, so far. I believe they need liquid nitrogen and shite right now.
Most, like the superconducting qubits Google and IBM are using, require liquid Helium and temperatures near absolute zero

What if I unplug it, though?

We’re still years to decades away from a QC powerful enough to implement Shor’s algorithm for breaking RSA encryption. Someone demonstrating error correction and logical qubits will be a much bigger deal than what Google showed recently. Still a neat result.
