Looks like it's just calling the crossref API

Go and Rust are more suited than Java for building graphical user interfaces that run cross-platform? That would be news to me.

Sure it can be done, but it's not exactly like there are well-established solutions for this.

If that was the goal, it seems terribly complicated when compared with podman.

Well, for one, KaTeX doesn't do "LaTeX" but a limited subset of the TeX equation syntax. As such, it can't handle more complicated macros or typesetting anything apart from equations.

And with that you're completely wrong, since strings in JavaScript are UTF-16.

It just so happens that your example consists of two UTF-16 codepoints.

(Node.js' Buffer uses UTF-8 by default).

This is not a very good explanation, nor is it useful for anything.

A single qubit is not useful for computation and the way it is written doesn't generalize to more than a single qubit. The code doesn't even really simulate a single qubit properly, since it doesn't use complex numbers.

What they call a "Rydberg gate" is not a gate at all.

Most of the text feels like it's written by an AI.

I find it slightly misleading that this is named after TeX, when it actually doesn't do TeX, but only has support for equations.

But I've already complained about that [1] when you presented your last project.

I suppose it's since it doesn't really support LaTeX but instead uses MathJax to render equations.

TeX is a a turing-complete language, picking some random subset of LaTeX commands would feel pretty arbitrary to me. In comparison, supporting full markdown syntax is pretty easy.

Actual research behind the article: https://arxiv.org/abs/2002.01491

This protocol depends on multipartite entanglement, so it does seem quite far away from being practical for anything yet.

If quantum routers were a solved problem and we had a quantum internet (last I checked, we do not), for this we would also need some form of 'coherent multicast routing'.

Want to be able to replace your keyboard, or get another one for the office easily? Buy a Cherry G80-3000.

The G80-3000 comes without NKRO, a very bendable case and PCB-mounted rather than plate-mounted switches.

A Leopold (for example) is much more pleasant to use and not so exotic that it's impossible to obtain a replacement.

That would be 2.

What's done in such an experiment is that we initialize a quantum state in a particular state (that this is possible is not actually obvious, but let's assume it's true) and then we make a lot of repeated measurements after different amounts of times.

So we're not talking about a single system, but instead about statistics about a set of measurements with systems that have been set up in the same initial state. (Each system only being measured once after a certain time after it's being set up).
