12 Feb 2026 - A team led by Jianwei Wang and Lin Chang at Peking University has demonstrated an integrated-photonics twin-field quantum key distribution (TF-QKD) network connecting 20 independent client chips across ten wavelength-multiplexed channels, with each channel surpassing the repeaterless bound at 370 km in spooled fiber. The results, published in Nature, achieve a total networking capability — defined ...

A team at the University of Science and Technology of China (USTC) published a paper in Science that quietly redrew the map of what device-independent quantum key distribution (DI-QKD) can do. Led by Bo-Wei Lu, Chao-Wei Yang, Run-Qi Wang, Xiao-Hui Bao, and the ever-present Jian-Wei Pan - the physicist sometimes called China's quantum communications supremo - the experiment demonstrated DI-QKD ...

India’s Department of Science and Technology (DST) published the “Implementation of Quantum Safe Ecosystem in India – Report of the Task Force.” This report, produced by a national Task Force under DST, lays out a strategic roadmap for transitioning India’s digital infrastructure to quantum-resistant security. The Task Force was chaired by Dr. Rajkumar Upadhyay (CEO of C-DOT) and convened experts ...

5 Feb 2026 - A team led by Jian-Wei Pan and Qiang Zhang at the University of Science and Technology of China (USTC) has demonstrated what the field has been waiting for: remote memory-memory entanglement that survives longer than the time it takes to create it. Published in Nature, the result uses trapped calcium-40 ions connected by 10 km of ...

Hong Kong’s central bank unveils a “Quantum Preparedness Index” to gauge how ready its banks are for the quantum computing era, underscoring a global push among regulators to future-proof financial security. Hong Kong’s de facto central bank, the Hong Kong Monetary Authority (HKMA), has announced the launch of a Quantum Preparedness Index (QPI) as part of its new Fintech Promotion ...

29 Jan 2026 - Quantum error correction is the wall that separates toy quantum computers from useful ones. Every qubit platform must eventually climb it. The first step up that wall is not correcting errors — that requires mid-circuit measurement and real-time feedback, capabilities that push the engineering envelope of any architecture. The first step is detecting them: identifying that ...

27 Jan 2026 — China's Micius satellite (墨子号), the world's first quantum communication satellite, has reentered Earth's atmosphere, according to tracking data from N2YO showing the spacecraft's status as decayed as of late January 2026. The ~635 kg satellite had orbited at approximately 500 km altitude in a sun-synchronous orbit since its launch on August 16, 2016 from the Jiuquan ...

The Cybersecurity and Infrastructure Security Agency (CISA) released a definitive advisory titled "Product Categories for Technologies Use Post-Quantum Cryptography Standards." This document, mandated by Executive Order 14306 (June 2025), fundamentally alters the procurement landscape for the United States federal government and, by extension, the global technology supply chain.    The advisory bifurcates the Information Technology marketplace into two distinct classifications: "Widely Available" PQC ...

The Citi Institute - a research arm of global banking giant Citigroup - published a stark warning titled “Quantum Threat: The Trillion-Dollar Security Race Is On.” In unequivocal terms, Citi’s analysts predict that within the next decade quantum computers are likely to become powerful enough to break widely used public-key encryption. They caution that the economic and geopolitical fallout of ...

The G7 Cyber Expert Group (CEG) - an international team of cybersecurity authorities co-chaired by the U.S. Treasury and the Bank of England - issued a landmark roadmap for the financial sector’s transition to post-quantum cryptography. This high-level plan, formally titled “Advancing a Coordinated Roadmap for the Transition to Post‑Quantum Cryptography in the Financial Sector,” is aimed at banks, financial ...

30 Dec 2026 - Exactly one year after Google's Willow became the first quantum processor to operate below the surface code threshold, China's USTC has matched the feat - and done it without the extra hardware that Google required. Researchers at the University of Science and Technology of China (USTC) have demonstrated quantum error correction operating below the fault-tolerance threshold ...

A new peer-reviewed study titled "Enterprise Migration to Post-Quantum Cryptography: Timeline Analysis and Strategic Frameworks" by independent researcher Robert Campbell has been published in the open-access journal Computers (MDPI). This paper provides one of the most comprehensive analyses to date of how long it will take enterprises to fully migrate their cryptographic systems to post-quantum cryptography (PQC). The findings are ...

Japan's NCO interim report sets 2035 as the migration target for government PQC transition. The alignment with the US and EU is deliberate, but Japan's dual-track approach combining PQC with its substantial QKD investment adds a dimension absent from Western roadmaps ...

21 Dec 2025 - Every scalable quantum computing architecture faces the same fundamental problem: individual qubits are small, but quantum computers are not just collections of individual qubits. They are networks. And the performance of a network depends not only on the quality of its nodes but on the quality of the connections between them. For silicon donor qubits, this ...

NIST published the final version of the Cybersecurity White Paper (CSWP) 39 – “Considerations for Achieving Crypto Agility: Strategies and Practices.” CSWP 39 elevates cryptographic agility from an oft-cited buzzword to a design imperative for both government and industry. The message is clear: organizations must be able to adapt their cryptography on the fly without breaking systems, treating agility as ...

18 Dec 2025 - China Telecom Quantum Group (CTQG) and QuantumCTek have deployed the Tianyan-287, a fully domestically produced 105-qubit superconducting quantum computer, for commercial cloud access on the Tianyan quantum computing platform. The system uses the same chip architecture as USTC's Zuchongzhi 3.0 - the processor that set the world record for quantum computational advantage in superconducting systems in ...

The Bank for International Settlements (BIS) and the Eurosystem published the results of Project Leap Phase 2, a massive technical trial testing PQC on the TARGET2 payment system (the Real-Time Gross Settlement system for the Euro). The project involved the Banque de France, Deutsche Bundesbank, the Bank of Italy, and Swift.    The headline finding was a success: the consortium proved they ...

Dutch startup QuantWare has announced VIO-40K™, a new 3D packaging architecture designed to build superconducting quantum processors with up to 10,000 qubits on a single device. This represents roughly a 100× increase over the scale of today’s largest superconducting chips. The VIO-40K approach uses a stack of chiplets - multiple layers of quantum chips and interposer modules - to deliver ...
