It denatures the lignin in the wood, which is the structure that binds the cellulose fibers together.  Without it, the fibers will shear apart easily.

You don't leave it like that, though. You re-bind with epoxy before you consider doing anything like throwing stones at it.

(Going on the article - from memory - prior attempts tried to remove the colour-infused lignin, this one just treated it to bleach out the colour. But 'damages' its interlinks somewhat. And once the wash is, in turn, washed out, it probably retains some lignin cross-link, before you ramp it up by epoxying it.)

I'd like to see what epoxyed cotton wool (or even uncarded sheep wool) would be like. Perhaps with minimal preprocessing (the non-cellulose wool needs scouring to at least clean/delanolin it). If it's cellulose-only treated wood we're actually getting, to compare with, it would save the whole 'dissolve everything else!' aspect by starting with near-pure cellulose (beyond standard deseeding and other cleaning up). Though it'd also be tempting to suggest also trying this with polar bear fur (famously clear and colourless and some hairs hollow, thus having transparency; though not actually fibre-optic), either method of farming this material is probably beyond the pale.

The student slaves research assistants would probably get hella extra credit for living through shaving a polar bear, though! Think of their GPA!

Shave the polar bears!

Reading his name would trigger it. Thinking of him would trigger it. No other circumstances would trigger it- it was strictly related to the concept of Bill Clinton entering the conscious mind.

The university of Delft managed to achieve a new milestone in quantum networking.

Where a stable quantum connection between 2 physcial points has already been achieved a few times, the research team in Delft now is the first to build a network connecting 3 physical points.

The distribution of entangled states across the nodes of a future quantum internet will unlock fundamentally new technologies. Here we report on the experimental realization of a three-node entanglement-based quantum network. We combine remote quantum nodes based on diamond communication qubits into a scalable phase-stabilized architecture, supplemented with a robust memory qubit and local quantum logic. In addition, we achieve real-time communication and feed-forward gate operations across the network. We capitalize on the novel capabilities of this network to realize two canonical protocols without post-selection: the distribution of genuine multipartite entangled states across the three nodes and entanglement swapping through an intermediary node. Our work establishes a key platform for exploring, testing and developing multi-node quantum network protocols and a quantum network control stack.

Haha sweet. Did anyone figure out how to reactivate the entanglement? Last I knew triggering it broke the quantum entanglement.

Now that they can do 3's I wonder if the third could be used to reactivate the entanglement on the other two somehow. That would enable quantum radios and later quantum internet.

EDIT2: I called matched pairs of quantum communication devices quantum radios because one is sort of a broadcaster and the other a receiver. I made it up and agree it's not a the best choice of term. I think we should call them Zagfllelligons, surely that will catch on. It IS closer to spelling Zap Brannigans after all, Kif.

Spoiler: image (click to show/hide)

EDIT:

It seems it's come a long way since I last read about it. What I poorly described above are known as Quantum transfer and Quantum Repeaters. I think when I last read about Quantum entanglements, they had just figured out quantum transfer and I thought hey this would be great if they had linked sets of 3 instead of linked pairs because with 3, one could be a control for the other two somehow if that's doable and transfer the entanglement state back once it's broken by triggering the link. I don't kniow how Quantum entanglements actually work with all the math, I just know the basic form and some of the potential applications.

EDIT3: I also thought I remembered another discovery that tied these together somehow more clearly, but that may be me remembering learning about Quantum Transfer shortly after it was published a while back.
