alt Hacker News> 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.
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.
