So they are not all in a superposition with each other? They talk about a million of these nanowires but that looks a bit like quantum dots?
What is Win 11 boot time on this processor ? Will it be supported in the next version of Windows ? /s

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.
Do you have other things you want to provide that your self-proclaimed ignorance would be helpful with?
Your comment could get an award for most toxic HN comment ever and that's saying something.

Lay people are welcome to read about the latest developments in science. They're also welcome to try to intuit theories related to those latest developments. It's a good way to flex your thinking skills. Experts are then welcome to weigh in on those intuitions and steer them along the right path. Even if you're completely wrong, expressing how you think about things is also helpful to others in case they also have si…
> 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.

I need HN's classic pessimism to know if this is something to be excited about. Please chime in!

What do they mean by >can create an entirely new state of matter – not a solid, liquid or gas but a topological state
There are in fact other forms of matter. In plasma you just have ions (instead of atoms/molecules) just zipping about. In neutron stars, you have pretty much only neutrons collapsed into a packed ball.
You can also make systems at higher levels of abstraction that have some of this matter or particle like behavior. A simple example is "phonons", which are a small packet of vibration (of atoms) that travels inside a solid much like a photon travels through space. I think phonons don't have a "mass", so they are not matter.
Here, they construct a quantum system, some of whose degrees of freedom behave like a matter particle. Qubits are then made from the states of this particle.
Are these actually even useful yet? Genuine question. I never managed to solicit and answer, only long explanations which seemed to have an answer of yes and no at the same time depending on who you observe.
The long explanations boil down to this: quantum computers (so far) are better (given a million qubits) than classical computers at (problems that are in disguise) simulating quantum computers.
