#2> Majoranas hide quantum information, making it more robust, but also harder to measure. The Microsoft team’s new measurement approach is so precise it can detect the difference between one billion and one billion and one electrons in a superconducting wire – which tells the computer what state the qubit is in and forms the basis for quantum computation.

Whenever I read about a scientific breakthrough I login to HN to see what the smart people think about it, and am disappointed if there isn't a post with hundreds of comments.

I wouldn't trust HN one bit (or one qubit) to comment usefully on this question, but presumably hundreds of people are already bugging Scott Aaronson to blog about it. He'll probably have a post in the next couple days saying whether we have permission to be excited.

This isn’t a forum of smart people. It’s a forum of asocial tech workers who write in authoritative prose but are just normal people at home staring blankly at a blue glow of a mental bug zapper
Quantum is just the next form of sampling the electromagnetic field. It’ll provide mesmerizing computational properties but not rewrite human DNA or beam our consciousness to another galaxy; it’ll fill up RAM and disk really fast with impenetrable amount of data it will take decades to analyze and build real experiments across contexts to verify. Tomorrow will still come and be a lot like yesterday for us.
All in all it’s more of the same
Even if it we do beam our minds it’s just a copy. These meat suits still gonna stop experiencing someday. Life for us isn’t going anywhere.

Being able to detect a single electron among billions sounds more like a good way to get entropy rather than something that can help with quantum measurements. At least that's my initial intuition being completely ignorant in Quantum Computing.
