IBM says quantum advantage arrives in 2026. A new Heron-Fugaku experiment provides the evidence. Whether it proves the claim depends on how you define “advantage.” ...

The inventor of BosonSampling and new NAS member says reputable QC hardware experts now tell him a cryptanalytic quantum computer should be possible by around 2029 ...

Three U.S. policy moves — NQI reauthorization, a quantum cybersecurity bill, and a Pentagon migration guide — show Washington building plumbing for the quantum transition ...

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 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 ...

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'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 ...

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 quantum computing ...

McKinsey’s 2026 Quantum Technology Monitor declares a “commercial tipping point.” The market analysis is useful, but the investment figures still deserve scrutiny ...

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 ...

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 ...
