Reading the article about how they filtered and cherry-picked specific regions, I got curious about the actual asymmetry computation, so I looked up the source code. Looking at it, they seem to have used memory offsets as if they were physical coordinates, but they're only looking at the array index order, not the actual values. x[::-1] isn't measuring physical coordinates; it's just reversing the array. So it seems this bias axis mentioned in the article only forms when things are symmetric. But in typical numerical computations, isn't it pretty common to reverse arrays like this? In this case, there must be a reason why the physical coordinates change. Should we be verifying invariants here? Sometimes I see people who find these kinds of issues and I think they're really amazing. Even after reading the article, tracing it, and debugging it, I kept wondering what the problem was..
Was pleasantly surprised to see the exact bug in here, in a "The Register" article of all places. Legg showed that fixing the bug invalidates the research. Seems Microsoft is responding to a clear problem with a vague dismissal.
Edit: Oh, The Register is a true tech paper, guess the name makes sense for that. Got mixed up cause there are a bunch of general papers called something Register.
You’d really think they’d really check everything and cross their t’s after their previous issues in marjorana fermion QC. I generally have a very high opinion of MS research, but this is getting a bit embarrassing.
Not the first time that a Nature publication's "too good to be true" results turn out to be based on simple programming errors... Nature 532, 210 (2016) was retracted after it was shown that a hand-coded gradient function, used in gradient descent, had a simple sign error (details in arXiv 2003.05808).
I guess Microsoft upper management doesn't understand anything at all about quantum computing and they are "scammed" by Microsoft research people in quantum computing telling them they are making breakthroughts, that in a few years that can become a real thing, etc. They just need to publish some impressive sounding papers a little bit once in a while and the thing keeps rolling.
May be it is just me but when I see all these quantum computing pseudo results I wonder how people can believe this thing has any hope to work at all so much it is ungrounded to reality.
All in all, the whole fundation of the quantum treatment is flawed in my humble opinion because of the idea of wave-packet collapse, when a measurement is done, is by itself completely unsound. However they assume it holds perfectly and base a ton on speculative calculations assuming that principle holds perfectly which is far from true.
Successful engineering and technology development is not done having a crazy idea that holds only based on a number of highly incertain assumptions but it needs solid ideas developed incrementally iterating from things we already know. First electricity, then basic electronics, the diode, then bipolar transistors, then J-FET, then MOSFET and so on.
TheRegister - like, say Viz - likes its lazy, outdated journalistic stereotypes and tropes.
That's not being critical of them; its their humour, they mimic the crassness and condescension of tabloid journalism, particularly that of the 70s and 80s (even tabloids have moved on).
When you see cliches like boffin, nanny state, egghead etc etc in a HN title, you can be reasonably confident its El Reg.
Yeah, El Reg has a whole house style around it at this point. I actually trust their write-ups more than press-release rehashes though - they dug into the actual GitHub repo and found the Python bug themselves instead of just quoting Microsoft's blog post.
I was surprised to see it - I thought "boffin" was good-natured but highly irreverent, like "nerd". But I can't imagine any publication writing the headline, "Computer nerd claims Microsoft's supposed quantum leap does not compute."
Does "pundit" even mean the same thing though? Boffin implies some hands-on expertise, however mocked; pundit is just opinion-for-hire. Swapping them in would flatten a distinction that's actually doing work in how these stories get framed.
Disagree that it dates anyone. El Reg uses "boffin" as deliberate house style, not because their writers are stuck in 1995. It's branding at this point, same as calling storage "spinning rust."
> boffins willing to go on the record as describing Microsoft's work as "unreliable" and perhaps even "fraudulent."
> Microsoft insisted its work is sound and in early June 2026 announced Majorana 2, a "next-generation topological quantum chip" it developed with the help of its own agentic AI.
AI hallucinates quantum computing bullshit as well or better than humans can hallucinate quantum computing bullshit. Couldn't have a better combination of technologies helping each other out.
> Microsoft's researchers made a basic programming mistake by evaluating the array index – the number identifying a value's position in an array – instead of the value to which the index refers.
I don't think research papers normally come with a simple portable way for others to rerun the calculations. At some point the code is complicated enough to be impossible to just proofread without running it.
I actually have been fiddling with something like this. Self publishing on GitHub, numbers that are run in real time. If code can be open-sourced, I think research can start to be. I started using linux in 2019, and honestly, though I don't use it now (windows-turned-mac man, sigh), open source is a solid concept.
Seen this exact class of bug tank a demo before, off-by-one in array indexing that nobody catches till someone reruns the numbers. We require a second engineer to actually execute someone else's analysis code before it goes in a deck. Cheap insurance, would've caught this in an afternoon.
