G7 urges governments, organizations to begin PQC transition, protect public key encryption from quantum threats - industrialcyber.co

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and the G7 Cybersecurity Working Group are urging governments and organizations to immediately begin transitioning to post-quantum cryptography, warning that quantum computing poses an urgent threat to current public-key encryption systems. The document focuses on risks posed by cryptographically relevant quantum computers (CRQCs), reaffirming collective efforts to address the threat.

Finding quantum advantage requires focused circuits

Su-un Lee’s fascination with the logic of planetary motion led him to the quantum realm as an undergraduate at Seoul National University in Korea. After arriving at the University of Chicago Pritzker School of Molecular Engineering in 2022, Lee began research identifying a critical requirement for realizing the potential of quantum computers. He reports that scientists need highly structured quantum circuits to achieve quantum advantage, suggesting current approaches may be too broad in their design. Lee explained his choice of UChicago PME, stating, “I was particularly interested in his group’s broad range of research across quantum information science, from fundamental theory to practical applications.” Structured Quantum Circuits Define Near-Term Advantage Lee’s research demonstrates that highly structured quantum circuits are essential for achieving quantum advantage, a finding that challenges assumptions about the potential of near-term quantum devices. He developed both classical and quantum algorithms to rigorously study the boundaries of these circuits, revealing limitations that previously hindered progress. This work moves beyond simply building quantum computers and focuses on how those computers are programmed to solve problems. Professor Liang Jiang also provided significant support, offering Lee the freedom to pursue independent research directions and skillfully connecting researchers with complementary expertise. He’s curious about a wide range of topics and has a great sense of which people and perspectives to bring together for a discussion.” The insights gained from this research were further refined through internships at IBM’s facility in Yorktown Heights, New York. During the summer of 2025 and again in 2026, Lee collaborated with experimental researchers to identify bottlenecks in current quantum devices as part of a large-scale project. He noted that being part of such a large collaboration for such an ambitious goal was a new experience for

Germany Deploys First Laser-Free Trapped-Ion Quantum Computer Inside Major Supercomputing Facility - Tech Times

By Caleb Pittmann Published: Sep 04 2026, 10:57 AM EDT Eleqtron.com Germany has switched on a quantum computer that controls its qubits with microwaves rather than lasers — a hardware distinction that, for the first time, allowed engineers to wire a gate-based trapped-ion system directly into one of Europe's most powerful supercomputers without the vibration-sensitive optical infrastructure that has historically kept such machines confined to specialty physics labs. On September 3, 2026, Forschungszentrum Jülich and the Siegen-based startup eleQtron officially inaugurated JION at JSC — the Jülich trapped-ION quantum computer — at the Jülich Supercomputing Centre (JSC) in North Rhine-Westphalia (NRW).The inauguration ceremony, held before NRW Minister-President Hendrik Wüst, Economics Minister Mona Neubaur, and Science Minister Ina Brandes, was also the occasion for two additional funding announcements: approval of a successor project called SQALING and a second project called Q-STAR.NRW, each receiving up to approximately €25 million (approximately $29 million USD) from EU structural funds and NRW state support, signaling that JION is a waypoint in a multi-step regional quantum computing strategy. Both successor programs were announced at the ceremony alongside the JION inauguration itself.Prof. Kristel Michielsen, who heads the Jülich Supercomputing Centre and leads the JUNIQ platform, described the system's role in measured terms. "JUNIQ provides access to a range of quantum computers and allows their performance to be compared," she said at the inauguration. "With JION, we are expanding this unique user platform to include a trapped-ion system from North Rhine-Westphalia and connecting it to our HPC infrastructure — for research and industrial applications."Prof. Astrid Lambrecht, Chair of the Board of Directors at Forschungszentrum Jülich, noted the broader intent: "In doing so, we are creating the conditions for combining quantum computing and high-performance

New method preserves distance in quantum error correction codes

Researchers at the University of Oxford have developed a new method to transform existing quantum error correction codes into a more dynamic form known as Floquet codes. The work introduces a Floquetification procedure that synthesises novel codes using only single- and two-qubit operations, simplifying implementation for complex systems. This procedure maintains the original code’s ability to protect data, with any qubit overhead scaling linearly with the complexity of the original code’s measurements. The team defined a distance-preserving rewrite that enables the transformation of error-correcting codes without changing their distance, guaranteeing that a single error in the resulting circuit creates at most a single error on the data qubits. Floquetification Procedure Converts Stabiliser Codes The qubit overhead introduced by this new method scales linearly with the weight of the largest measurement in the original code, offering a quantifiable trade-off for implementation. This relationship means that stabiliser codes requiring more complex measurements will necessitate proportionally more physical qubits in the resulting Floquet code, a predictable cost for increased complexity. Researchers Benjamin Rodatz, Boldizsár Poór, and Aleks Kissinger, all affiliated with the University of Oxford, detailed this process in a publication published September 3, 2026, outlining a method capable of transforming any stabiliser code into a new code using only single- and two-qubit operations. This simplification is particularly significant as it eases the practical challenges of implementing complex quantum error correction schemes. Central to this transformation is the application of the ZX calculus, a graphical language for representing and rewriting quantum circuits, but the team addressed a critical limitation within this framework. They defined a distance-preserving rewrite that enables the transformation of error-correcting codes without changing their distance, ensurin

GCISO urges New Zealand agencies to invest in post-quantum computing by 2030

New Zealand government agencies are being urged to invest in post-quantum computing (PQC) solutions before 2030, as the arrival of a fully error-corrected quantum computer threatens to unravel current encryption methods. This push follows recognition of a growing practice described as “harvest now, decrypt later,” or HNDL, where encrypted data is collected for future decryption. “Anything you send now might not be secure in five years,” warns Professor David Hutchinson of Otago University, who advises the OECD on quantum computing. Virtually all current security protocols, from internet communications to banking PINs, rely on factorization of prime numbers, a system vulnerable to future quantum attacks. HNDL Attacks and the Threat to Current Encryption This tactic, recognized internationally and recently detailed in a US Federal Reserve paper, involves collecting data now with the intention of exploiting quantum computing power to unlock it when available. Hutchinson said that current internet security protocols, banking systems, and information kept safe within government largely depend on a security protocol based on the factorization of prime numbers, which is used whenever we share information, whether through the internet or when entering a PIN at a bank machine. The OECD highlighted HNDL attacks last year as justification for immediate action, noting that transitioning to quantum-resistant cryptography could take up to 20 years given the scale of systems involved. Treasury reports from last year reveal concerns that agencies are not adequately prioritizing cyber security investment and preparedness for emerging threats. The GCISO reported to Treasury that investment proposals demonstrate agencies are not dedicating enough time and resources to address cyber security challenges, adapt to emerging technologies, and prepare for future threats.
