content: Well, MS has significant experience in quantum software already (software that's in several states at the same time without anyone knowing what's happening under the hood until we observe it).Jokes aside, let's see where it leads.https://en.wikipedia.org/wiki/Majorana_1#Controversy

content: is there some simulation or graph or something made with quantum computers that can be represented on a normal computer like the solution to some flow problem or field strength or whatever in the form of a graph, video, drawn path, figure.. something that we can see that would not be possible to solve with a normal computer?i.e. something with atoms, photons, antimater, neutrinos, muons, humming birds or maybe even a math graph?

content: Google has qsim, a quantum circuit simulator:https://quantumai.google/qsimNot sure it really does what you'd expect though and it requires a pretty beefy computer, although if you limit it to a couple qubits, it should be usable on a modest desktop computer.

content: I know you can simulate a quantum circuit but I mean I want to see what these quantum computers solved.Whenever sandia gets a new super computer they publish some simulations done on it (like golf ball aerodynamics). I want to see something that a quantum computer developed, solved, rendered, graphed, determined, etc

content: I don't know if thats a quantum computer, its a quantum communicator. I thought they were supposed to solve some kind of problems/simulations faster, i.e. for a 1 second long simulation of a _____ (quantum simulatable thing, I can guess : quark, anti electron, exotic phase of matter, black hole) with a 1ms time interval, a conventional super computer takes 50 years but a quantum computer finished in 5 minutes.isent that the whole point?I thought it was supposed to do some math function faster, kind of like how we have a DSP processor for efficient division? but its some other math operation for a QC?

content: It is not even "communication", it is secure key exchange using quantum principles (QKD-Quantum Key Distribution). It exists today and has nothing to do with quantum computers.

content: 2 majorana researcherSergey Frolov and Vincent Mourikcame out to talk about thisthey think that microsoft is bullshitting, againthis is reflected by another reporthttps://physicsworld.com/a/experts-weigh-in-on-microsofts-topological-qubit-claim/Quotemaybe they will retract the paper again?yep this is not the first timeso many hyped researchthe 2022 paper was revised 4 timesand on first glance i spotted a diagram error

content: Microsoft does not exacly have a reputation as a "gold standard" of integrity.For example: Bill Gates had an affair with a Microsoft employee, which they covered up.They then gave him "the boot" for "different reasons".Plus, they are supposed to makesoftware!Not hardware!It's in the name!Microsoft!

content: Well, if the quote I gave earlier was not a pile of BS already, I don't know what is.Sure, you may have thought it was just marketing talk and did not reflect the actual technology.Turns out that it very likely does.
