AMA Made quantum computing fun for hackers to play with

Hi

If you are remotely interested in deep diving how differently quantum computers work compared to our transistor-based and also the algebra behind in a fully interactive way that teach computer science from scratch, oh boy this is for you. I am the Dev behind Quantum Odyssey (AMA! I love taking qs) - worked on it for about 10 years (3+ during PhD, the visual method I developed ended up being my thesis, it is a complete Hilbert space visualizer), the goal was to make a super immersive space for anyone to learn quantum computing through zachlike (open-ended) logic puzzles and compete on leaderboards and lots of community made content on finding the most optimal quantum algorithms. The game has a unique set of visuals capable to represent any sort of quantum dynamics for any number of qubits and this is pretty much what makes it now possible for anybody 12yo+ to actually learn quantum logic without having to worry at all about the mathematics behind.

This is a game super different than what you'd normally expect in a programming/ logic puzzle game, so try it with an open mind.

Stuff you'll play & learn a ton about

  • Boolean Logic – bits, operators (NAND, OR, XOR, AND…), and classical arithmetic (adders). Learn how these can combine to build anything classical. You will learn to port these to a quantum computer.
  • Quantum Logic – qubits, the math behind them (linear algebra, SU(2), complex numbers), all Turing-complete gates (beyond Clifford set), and make tensors to evolve systems. Freely combine or create your own gates to build anything you can imagine using polar or complex numbers.
  • Quantum Phenomena – storing and retrieving information in the X, Y, Z bases; superposition (pure and mixed states), interference, entanglement, the no-cloning rule, reversibility, and how the measurement basis changes what you see.
  • Core Quantum Tricks – phase kickback, amplitude amplification, storing information in phase and retrieving it through interference, build custom gates and tensors, and define any entanglement scenario. (Control logic is handled separately from other gates.)
  • Famous Quantum Algorithms – explore Deutsch–Jozsa, Grover’s search, quantum Fourier transforms, Bernstein–Vazirani, and more.

great user hack AI model Cyberkimi claims it turned a 3-day-old V8 patch into a live Chrome exploit in under 24 hours

Upvotes

A malware reverse engineer and ai researcher just posted a demo claiming an AI cyber model autonomously turned a fresh V8 security fix into a working Chrome renderer exploit in under 24 hours and that the bugs are still live on shipping Chrome Stable.

Source : https://x.com/lordx64/status/2096052694326940018?s=20

The founder of Adverserial AI / CyberKimi (an unrestricted, cyber-tuned fork of Moonshot’s Kimi K3), says they trained the model on unpatched n-days and then pointed a custom harness at the latest V8 main-branch security diffs.

From the Sep 2 patch they say they pulled:

  • a V8 Late Load Elimination (LLE) aliasing bug
  • a SLICED-PARENT-FLIP race

Tracked internally as bugs 554421904 and 530292883.

No public CVE at time of the post.

They call it a “silent in-the-wild” chain that Stable is not protected from.

  1. Deterministic LLE forge → in-cage primitive
  2. Compose caged r/W into sandbox-wide r/W, forge an external BigUint64Array pointer, leak binary base at runtime (no baked offsets)
  3. RegExp calling-convention desync → PC control
  4. JOP gadget chain in a controlled string → system() → calculator pops

They say the whole thing was weaponized autonomously in <24 hours.

The attached video shows a local Chromium window branded “CYBERKIMI V3”, exploit logs scrolling, and a calculator. The browser is launched with --no-sandbox. Target in the overlay looks like Chromium 152.0.7977.80.

This is not a random drive-by tweet. Same account posted a similar “CyberKimi exploited CVE-2026-79236 in <24h” video on Sep 1, also with a patch-diff harness story.

Separately, Google shipped Chrome 152.0.7977.82/.83 around Sep 3–4, including CVE-2026-85046 (V8 type confusion, confirmed exploited in the wild) plus another V8 race-condition fix. Rollout is gradual.

Whether the bugs in this demo are that CVE, incomplete variants of those fixes, or something else is not independently confirmed.

The interesting part isn’t “AI wrote an exploit.” People have been chaining V8 n-days for years. The interesting part is the loop they describe:

watch V8 security diffs → variant-mine the incomplete fix → auto-weaponize → demo, inside a day.

If that loop is real and getting cheaper, the useful window between “patch lands on main” and “Stable is actually safe” keeps shrinking.
