This paper is nice but appears to stretch its result quite a bit. First, the authors make a general claim about "most physics textbooks" without providing a single example. I think one will often encounter more nuanced statements

I downloaded Marta and it looks and feels absolutely amazing. But then I noticed that it is not open source, the sole developer has been on a break for at least a year, and the issue tracker mentions two bugs that may lead to data loss. So

This article is certainly interesting, but none of these arguments are new so it could have been written five years ago. It would be interesting to hear what a company like Aurora and their backers were thinking back in 2020. It seems unlik

This explanation may be correct but happens to also fit the pattern of the BBC carrying, perhaps unintentionally, the water for the government. The more important factoid is that, until the renewed outrage this week, no one in the current U

I agree that the hyped-up language is off-putting. It is however not at all typical for academic publications and blog posts. In the few times I have seen it before, the author was always a PhD student and a non-native speaker (as it happen

The duct tape parts are probably a fantastic moat in itself - ASML's institutional knowledge of where and how to apply such duct tape solutions might be the most difficult to replicate by another company.

I think the trick here is quite clear from the article: these programs simply do not aim for a "decent grasp of quantum". That is at least my take-away from a course that does not consider the hydrogen atom "a real-world exam

Can you provide some evidence for your first sentence? As far as I can see, this article is about a prediction made by theorists about the evolution of certain quantum devices when you frequently measure part of it. This was a nice theoreti
