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 as 190,000 physical qubits — a roughly 4.7× reduction from the current monolithic baseline. The ...

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 Services, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, the Linux Foundation, Microsoft, NVIDIA, and Palo Alto ...

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 Westerbaan, explicitly cites last week's Google Quantum AI ECC-256 resource estimates and Oratomic's 10,000-qubit Shor's ...

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. The result, described in a pre-print on arXiv currently undergoing peer review, demonstrates a technique ...

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 report, dated 9 March 2026 and authored by Dr. Michele Mosca (co-founder and CEO of ...

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 computation by gauging logical operators", appears in Nature Physics (DOI: 10.1038/s41567-026-03220-8). The technique treats logical ...

When China's National People's Congress approved the 15th Five-Year Plan on March 12, 2026, it completed a journey that had been building for over a decade. Quantum technology, once buried deep in academic research budgets, emerged at the top of Beijing's list of seven "future industries" designated as new engines of national economic growth. Above biomanufacturing. Above hydrogen energy. Above ...

Scottsdale, AZ — April 1, 2026 — QuantumShield360 AI, a next-generation quantum-resilient cybersecurity platform leveraging AI-powered lattice synergies, today announced it has completed a full, end-to-end migration to post-quantum cryptographic standards across its entire technology stack — becoming the first company in history to achieve total quantum resilience. "While Fortune 500 companies are still conducting cryptographic inventories and debating algorithm ...

31 Mar 2026 - On the same day that Google Quantum AI published its landmark ECDLP-256 resource estimates showing fewer than 500,000 superconducting qubits could break cryptocurrency cryptography in minutes, a team from Oratomic, Caltech, and UC Berkeley quietly dropped a paper making an even more startling claim about qubit count: Shor's algorithm can be executed at cryptographically relevant scales ...

31 Mar 2026 - Google Quantum AI has published a 57-page whitepaper demonstrating that the quantum resources needed to break the elliptic curve cryptography protecting Bitcoin, Ethereum, and virtually every major cryptocurrency are roughly an order of magnitude smaller than previously estimated. The paper, titled "Securing Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities: Resource Estimates and Mitigations" and co-authored with researchers ...

27 Mar 2026 - Every March, the Office of the Director of National Intelligence publishes a document that most Americans will never read but that quietly shapes trillions of dollars in defense spending, intelligence priorities, and technology policy. The Annual Threat Assessment (ATA) is the Intelligence Community's official, unclassified evaluation of the threats facing the United States - a consensus ...

25 Mar 2026 - The company building the quantum computer is telling you the clock is running out. That should get your attention. On March 25, 2026, Google published a brief but consequential blog post authored by Heather Adkins, VP of Security Engineering, and Sophie Schmieg, Senior Staff Cryptography Engineer. Buried beneath a deliberately understated title - "Quantum frontiers may ...

24 Mar 2026 - In 1998, Bruce Kane published a single-page proposal in Nature that launched an entire subfield of quantum computing. The idea was elegant: use the nuclear spins of individual phosphorus atoms embedded in a silicon crystal as qubits. Silicon offered long coherence times. Phosphorus offered an addressable spin. And the surrounding semiconductor infrastructure — the lithography, the ...

21 Mar 2026 - A curious thing happened in cybersecurity Slack channels and LinkedIn threads over the last few weeks: security professionals who had been dragging their feet on post-quantum cryptography migration suddenly had a new reason to wait. A paper published in the Proceedings of the National Academy of Sciences by Tim Palmer, an emeritus professor of physics at ...

15 Mar 2026 - When Clémence Chevignard, Pierre-Alain Fouque, and André Schrottenloher submitted their latest paper to EUROCRYPT 2026, they already had a track record that the cryptographic community was watching closely. In 2024, the same team at INRIA Rennes had published a method that slashed the qubit requirements for quantum factoring of RSA integers - work that Craig Gidney ...

10 Mar 2026 - Quantinuum researchers have demonstrated quantum computations using up to 94 error-detected logical qubits and 48 error-corrected logical qubits on the company's 98-qubit Helios trapped-ion quantum processor. The work, published as a pre-print on arXiv, reports "beyond break-even" performance across multiple benchmarks — meaning the encoded logical qubits outperformed their unencoded physical counterparts. The team used a ...

China's Origin Quantum Computing Technology Co. has made its quantum operating system, Origin Pilot, available for free public download - a move that multiple sources describe as the first time a quantum computer OS has been offered for local deployment anywhere in the world. The release, announced February 26 through the Anhui Quantum Computing Engineering Research Center and widely covered ...

7 Mar 2026 - On Friday afternoon - the traditional Washington burial ground for news you'd rather not have scrutinized - the White House released "President Trump's Cyber Strategy for America," the administration's long-delayed national cybersecurity strategy document. Originally expected in January, the strategy outlines six policy pillars that will ostensibly guide the nation's cybersecurity posture going forward. The document ...
