No, the sky isn't falling, but Q Day is coming, and it won't be as expensive as thought.

Cool. Call me once they do break traditional encryption with a quantum computer.

Yeah as soon as someone fixes the instability of quantum computing to the point u can get enough qbits. This story has been going on for 30 years now. But just to be safe its nice to see places slowly moving to post quantum encryption a lot of things have already made the leap

The difference is that 10 years ago you needed billions of stable qubits, now you need 10k stable qubits.

And 10 years ago you had one or two stable qubits in the lab, now you have thousands.

Sure. So itll be cracked in a week or so, id rather wait about hearing about it then.
