What’s Happening in Quantum — and What It Means
IonQ Publishes Complete Fault-Tolerant Blueprint for Trapped Ions “The Walking Cat Architecture”
IonQ's 110-page preprint details a complete fault-tolerant quantum computer architecture built entirely on qLDPC codes. The numbers are impressive, but every claim rests on hardware that doesn't yet exist at scale ...
Coinbase Quantum Paper: What It Gets Right, Wrong, and Misses
Coinbase assembled heavyweights like Scott Aaronson and Dan Boneh to assess quantum threats to crypto. Their paper is serious, measured, and technically sound. But it underestimates how fast the ground is shifting beneath blockchain cryptography ...
Nature Reviews Publishes the Definitive CMOS–Spin Qubit Compatibility Assessment
A comprehensive review from Dzurak's team maps exactly where silicon spin qubits align with existing CMOS manufacturing — and where they diverge. The implications for scaling to millions of qubits are more nuanced than the headlines suggest ...
IonQ Photonic Interconnect: First Networked Commercial Quantum Computers
IonQ's photonic interconnect demonstration links two commercial quantum computers via entanglement for the first time. The milestone is real and strategically important - but the absence of fidelity and rate numbers in the announcement demands closer scrutiny ...
QuEra Achieves 2:1 Physical-to-Logical Qubit Ratio With Ultra-High-Rate qLDPC Codes
A QuEra–Harvard–MIT collaboration demonstrates qLDPC codes that encode more logical qubits than they consume in overhead — a 2:1 physical-to-logical ratio that enters the Teraquop regime. This is a simulation result, not an experiment. But if it holds up, it rewrites the economics of fault-tolerant ...
NVIDIA Ising: Open AI Models for Quantum Calibration and Error Correction
NVIDIA's Ising family brings AI-driven automation to quantum calibration and error correction decoding — two bottlenecks standing between today's noisy qubits and fault-tolerant quantum computers. The strategic play underneath matters more than the benchmarks ...
Architecture Matters as Much as the Algorithm: Q-CTRL’s Heterogeneous Quantum Computer Design Cuts RSA-2048 to 190k-381k Qubits
9 Apr 2026 - Researchers at Q-CTRL, a quantum infrastructure software company headquartered in Los Angeles and Sydney, have published a paper introducing Q-NEXUS, a heterogeneous quantum computing architecture that claims to reduce the physical qubit requirements for factoring 2048-bit RSA integers to as few ...
Anthropic’s Mythos Preview and the End of a Twenty-Year Cybersecurity Equilibrium
8 Apr 2026 – Anthropic yesterday announced Claude Mythos Preview, a frontier AI model that can autonomously discover and exploit zero-day vulnerabilities in every major operating system and every major web browser. Alongside the model, Anthropic launched Project Glasswing, a defensive coalition including Amazon Web ...
Cloudflare Joins Google: Two Internet Giants Now Say 2029 for Post-Quantum Migration
7 Apr 2026 – Cloudflare, the infrastructure company that handles a significant share of global internet traffic, today announced it is accelerating its post-quantum cryptography roadmap and targeting 2029 for full post-quantum security — including, critically, post-quantum authentication. The announcement, authored by Cloudflare Research's Bas ...
QuiX Quantum Achieves First Below-Threshold Error Mitigation in Photonic Quantum Computing
5 Apr 2026 - QuiX Quantum, a Netherlands-based photonic quantum computing company, announced it has demonstrated below-threshold error mitigation on a photonic quantum computer for the first time, in collaboration with NASA's Quantum Artificial Intelligence Laboratory (QuAIL), the University of Twente, and Freie Universität Berlin ...
Quantum Threat Timeline Report 2025: Record Predictions, But Can the Survey Keep Up?
5 Apr 2026 - The Global Risk Institute (GRI) and evolutionQ Inc. have published the seventh edition of their annual Quantum Threat Timeline Report, the longest-running expert survey dedicated to estimating when a quantum computer will be capable of breaking widely deployed public-key cryptography. The ...
Gauge Theory Meets Quantum Computing
April 2, 2026 - Dr. Dominic Williamson of the University of Sydney and Theodore Yoder of IBM have published a new method for performing fault-tolerant logical measurements on quantum error-correcting codes that dramatically reduces the physical qubit overhead required. The paper, titled "Low-overhead fault-tolerant quantum ...
