Quantum-PKI-nerd blogje. De toekomst is Quantum dus ik ben vast begonnen om mij daarin te verdiepen en dat ook daadwerkelijk te bouwen. Een leuk projectje die tot een goed einde is gekomen maar nog totaal niet bruikbaar is voor de normale wereld. 😎 "Volledig Post-Quantum Cryptografie website" https://www.cryptophobia.nl/blogs/213-volledig-post-quantum-cryptografie-website.html #PQC #Quantum #Apache #Ubuntu

This is way above my pay grade, and I've only read the article, not the actual technical work underneath it (because my maths is insufficient to know what it's talking about, so there's not a lot of point). But it sounds really interesting. https://muellerberndt.medium.com/how-observer-path-holography-improves-on-the-standard-model-and-general-relativity-c971c376027e I've never heard of "observer patch holography" (note typo in slug text), but a theoretical framework which has just a single free variable but lets you derive general relativity and the standard model, correctly predicting a bunch of magic numbers that we input as free variables into the standard model, is interesting as hell. Maybe someone smarter than me has already looked at this and debunked it. Sabine doesn't seem to have done a video on it (or I missed it). And "one guy with four information theory axioms solves all of physics' problems" is definitely on the Hollywood-script end of the plausibility scale, but who knows? Weirder things have happened. @cenobyte@mastodon.thirring.org - thought of you, of course. #StandardModel #physics #GeneralRelativity #GR #ObserverPatchHolography #OPH #quantum

This from Scott Aaronson was good: "Just like the more AI does, the less patience I have for arguing with anonymous blog commenters who treat any benefits from AI as some weird future hypothetical that it’s my job to prove, so it is with quantum advantage. Scalable fault-tolerance is still in the future, actual usefulness is still a question, but pending some breakthrough in complexity theory, the reality of quantum advantage is no longer a live question." (in response to Qedma and IBM showing quantum advantage on simulating Floquet dynamics with a 74-qubit IBM device, with corroboration on Quantinuum hardware) https://scottaaronson.blog/?p=9979 https://arxiv.org/abs/2607.24937 #quantum

Weekend Reading care of TechAptitude! Like the global “race” for AI leadership, Quantum Technologies have enormous geo-political dimensions that span multiple domains including national security, technological sovereignty, economic advantage/disadvantage, and military power. In this TechAptitude post we dive into this Geo-Political implications of Quantum Technologies. Enjoy! https://techaptitude.substack.com/p/quantum-technologies-and-geo-politics #Quantum #QuantumComputing #Geo-Politics #TechAmplitude #QuantumTechnologies

Quantum Technologies and Geo-Politics

On the Geo-Political implications of Quantum Technologies – Is it realistic to think Quantum Technologies can be controlled and contained by individual nation states?

New #Perspective published in Quantum: Charting separability and entanglement of diagonal Dicke states Dicke states are multipartite quantum states first introduced in \cite{Dicke1954} to describe the collective excitations of $N$ two-level atoms coupled to a single-mode electromagnetic field. They span a subspace of only $N+1$ dimensions, which contains all fully symmetric states under particle pe https://quantum-journal.org/views/qv-2026-08-07-87/ #OpenScience #Quantum #Research

This story is in the form of poetry. #audiobook #narration #quantum #video This reading is Quantum Cake a la Solvay by Pippa Storey, who has a master's in physics and a doctorate in quantum physics. Now she researches MRI. The quantum concepts are dice, entanglement, light, Planck's constant, quantum states, Schrodinger's cat, tunnelling and wavefunction. See how many references you can spot. https://youtu.be/U2zuIry0qws rjb

A job where your observing collapses the wavefunction in the direction your client wants. #audiobooks #recording #video #YouTube #quantum This reading is Powers of Observation by Charmaine Smith, who currently collapses the wavefunction in California. She likes to play with words and her cat, who outsmarts the box every time. The quantum concepts are the act of observation, math and wavefunction. After a while it gets to be a lot to think about. https://youtu.be/kx9C0ePVKa8 rjb

A #Seattle startup called #Interlune says its Cold Capture process takes advantage of cryogenic distillation to produce a rare and expensive type of helium that's used in #quantum computers. The process can be used on Earth - and on the #moon, where helium-3 is more abundant. https://www.geekwire.com/2026/interlune-helium-3-cold-capture-moon/ #Space #Helium3 #Space #Tech
Interlune extracts helium-3 from ordinary helium, demonstrating a process it plans to use on the moon

This from Stanford's Mauritz Kop (founder of their Center for Responsible Quantum Technology) on the array of #quantum-related challenges the world is facing, and the US government's largely disjointed (though recently improving) approach was pretty good: https://warontherocks.com/cogs-of-war/before-q-day-the-race-to-quantum-first/ 1/2

Notable quote: "No document yet addresses what happens if these sensors shrink, network together, and fuse with artificial intelligence into a surveillance layer. In the future, a drone-borne magnetometer above a street protest could map vehicles, weapons, cabling, and movement, then fuse those signatures with video and phone-location data: an “X-Ray City.” The same sensor families are already being tested for brain imaging in ordinary rooms. While those applications are speculative, they belong in any sensing rulebook written now." #quantum 2/2

After the White House quantum summit, I tested the claim that America built "every layer of the quantum stack." Eight layers. Named researchers. Primary sources. Quick scorecard: The PQC algorithms (ML-KEM, ML-DSA, SLH-DSA) that NIST standardized and that EO 14412 mandates for federal systems? Designed almost entirely by Europeans and Canadians. CWI (Netherlands), Bochum (Germany), IBM Zurich (Switzerland), ENS Lyon (France), Waterloo (Canada). NIST ran the process — that's a real institutional win. But the algorithmic content is international. The enabling infrastructure is even more striking. Dilution refrigerators from Finland (Bluefors) and UK (Oxford Instruments) dominate the market that cools US superconducting quantum computers. Domestic manufacturing exists (Maybell in Denver, Bluefors's Syracuse operation) but the US remains substantially dependent on European-headquartered suppliers. Control electronics from Switzerland (Zurich Instruments), Israel (Quantum Machines), Germany (Rohde & Schwarz). The CHIPS Act quantum investments are partly a response to these dependencies. On the science side: Josephson junction predicted at Cambridge (1962). First superconducting qubit demonstrated at NEC Japan (1999). Surface code traces to Kitaev (Russia). Steane code from Oxford. qLDPC codes from French and Russian mathematicians. The US built the strongest commercial integration and scaling layer. That is a real and hard-won capability. It is not the same as sole authorship of the entire stack. Policy implication: "we built everything" leads to different supply chain decisions than "we built the best integration layer, and it depends on allied supply chains." The second framing is more accurate and produces better policy.

Dabbar says America built every layer of the quantum stack. I tested that claim layer by layer. The record is more international.
