The 200 seconds refers to a questionable quantum computing paper published by Google that's been heavily disputed. As I said, you've confused quad and quantum. It also wasn't an encryption crack - it was a mathematical calculation that Google reckons would take 10,000 years using conventional computing but others think would take a matter of a few days. I don't have the maths ability to judge who is right.Oh well, I’m clearly not as smart as you, we might have to agree to disagree.
Perhaps if you had been following what I’ve been following the ‘200 seconds’ would have made immediate sense to you, and you would know what it referred to, and how long the previous estimate was.
We've known for ages that quantum computing has the potential to make existing encryption essentially obsolete. Rather like nuclear fusion, the question is how to turn theory into reality.
There are also any number of other problems beyond simple computing power as I mentioned previously. Like with AI, army officers have a habit of treating cyber as the second coming of Jesus without really understanding much about it.
