🥁Drumroll for our incredible Superposition Sponsors, Quside! Our first ever official quantum electronic badge sponsors for Quantum Village @ DEF CON 34! With their support we were able to inspire over 30,000+ hackers and cybersecurity experts at the LVCC #DiffusionUnphased #QRNG #quside #defcon34

What would you ask a Nobel Laureate in Physics about quantum computing if you had the chance? Well, at Quantum Village @ DEF CON 34 this year, THAT CHANCE IS YOURS! We have the inimitable John Martinis, CTO of Qolab and Nobel Prizewinner in Physics 2025, coming to do the honours!

Got a question about quantum computing for a Nobel Laureate? Be there, @quantumvillage.bsky.social at @defcon.bsky.social - 1130, Saturday!

Here’s a google form to put your burning questions into: forms.gle/2rqM3cpUJdcQ... See you there!

give a talk on quantum computing and security at the village, Hall 2, 1130 on Saturday, but this will be followed by an extended Q&A session and we’d love to get your questions to put to the Prof! Where: Quantum Village, Hall 2, LVCC When: Talk @ 1130, Q&A @ 1200+

Microsoft is too busy with delivering a useful topological quantum computer by 2029 to worry whether their Majorana qubits actually work. "This notion of having peer reviews and publications doesn't work in this fast-moving world right now. This paper thing is kind of boring now." archive.ph/xGlb7

We're quite excited to have Prof. Martinis coming this Sat at DEF CON... Be there, and get your questions in!

In the spirit of writing more notes now that I'm attending more public meetings on subjects such as this, here's a nifty note about converting hidden shifts into hidden subgroup problems for quantum cryptanalysis: presheaf.blogspot.com/2026/07/note...

~25 years ago I crashed on a friend's couch before an interview. his dad, a former pastor, asked me what I was interviewing for, so I said, "Unix Administrator". he got a confused look for a moment, then started laughing, then asked me how I found enough eunuchs to need an administrator 😆

I'd love to see the survivorship stats on this... How many one shot maths conjecture runs came up with utter tosh vs. this one big win?

The "Life in Britain" citizenship test is a glorified pub quiz designed around English, not British, history.

I wrote back in November about how easy it was to find leaked passport photos and driver's licenses online. The spills have only gotten worse in the months that age verification laws rolled out. We're reaching a point (if not already) where our government IDs aren't worth shit in the digital world.

This was quite fun. Fun fact - the substitutions for x*y, -x, and x^{-1} are minimal (by exhaustive search). Enjoy!

I should be working, and yet...

I’m not over on the other platform anymore but this deserves sharing. Veneer finally starting to crack at some of these places.

#Quantum + #AI starts here!! We added an MCP server to make the world's first AI native Agent Ready QRNG! Take a look: github.com/QuantumVilla... This endpoint exposes the QRNG status, the health of the generated bits, and if course gives access to the whitened entropy!

Agentic Quantum, anyone?

Update; this is now the first AI Agent native QRNG! MCP server ready to go. 🦞🔗⤵️
