Why Blockchain???s Quantum Defense May Already Be Hidden in Mathematics
1+ hour, 23+ min ago (1031+ words) Home > Opinion > Why Blockchain’s Quantum Defense May Already Be Hidden in Mathematics The discussion about quantum threat in the crypto sector has moved beyond speculation. Migration to post-quantum cryptography does not require discovery of new mathematical structures. It requires coordinated…...
I'm Building a Post-Quantum Bitcoin in Rust — and a Test Caught a Real Consensus Bug Tonight
4+ hour, 22+ min ago (356+ words) Most ransomware tools stop at detection. Most Bitcoin forks stop at marketing. This post is about neither — it's about building a Bitcoin whose signatures survive Shor's algorithm, and what "fair launch" means when you actually mean it. The first coinbase…...
Quantinuum achieves 10 physical qubits per logical qubit—4.6×10⁻⁵ error rate without post-selection｜QNews_channel
2+ day, 7+ hour ago (577+ words) The Fact: Quantinuum has experimentally verified a new error-correction architecture, "Helix," on its 98-qubit commercial machine, Helios. The logical memory error rate is 4.6×10⁻⁵ per cycle. The paper is arXiv:2609.03194 (submitted September 2). Industry Shift: Logical qubit error rates have often been…...

Ethereum sets 2029 quantum target as Hegotá takes shape
12+ hour, 37+ min ago (1310+ words) Ethereum has set a December 2029 target for a quantum-resistant Layer 1 while moving Frame Transactions toward Hegotá and developing execution proofs, privacy tools and a new consensus design. As crypto.news reported in its coverage of the roadmap, Ethereum’s 2029 plan now…...
For more than a century, quantum theory has said a vibrating object should lose energy in discrete packets even though its motion appears to fade smoothly. Now physicists have watched a microscopic resonator lose its final phonon in real time, jumping abruptly from one quantum of vibration to none.
12+ hour, 44+ min ago (1103+ words) A superconducting qubit followed a nanomechanical resonator from its one-phonon state to the ground state, revealing a discrete jump while also exposing the readout's own back-action. By Lab Report · Edited by Lachlan Brown Published September 20, 2026 · How we edit A ringing…...
