Researchers from the University of Sydney and IBM have pinpointed measurement-induced idling noise as a major source of errors in superconducting quantum computers. Using a 156-qubit IBM Quantum Heron r2 processor, the team demonstrated that mid-circuit measurements — essential for quantum error correction — force other qubits to idle, introducing significant noise. By redesigning error-correction circuitry to reduce idling time, they improved logical qubit survival rates from below 90% to over 96% per error-correction cycle. The findings, published in Nature Communications, provide quantitative benchmarks for the performance requirements of error-checking operations and offer a clearer roadmap for scaling fault-tolerant quantum systems.

Sắc lệnh hành pháp 14409 của Mỹ yêu cầu các cơ quan liên bang và nhà thầu phải chuyển sang mã hóa hậu lượng tử (PQC) vào năm 2030 và xác thực hậu lượng tử vào năm 2031, nhằm ngăn chặn các cuộc tấn công "thu thập giờ đây giải mã sau". Cloudflare khuyến nghị cần làm rõ tiêu chuẩn "chuyển đổi", ưu tiên khả năng thích ứng mật mã (crypto agility) và thúc đẩy sự thống nhất toàn cầu về thuật toán NIST để tránh phân mảnh.
Lập trình viên nên đọc bài này để hiểu cách chuyển đổi sang các giải pháp mã hóa chống lượng tử (post-quantum) không chỉ là một yêu cầu pháp lý mà là một chiến lược bảo mật cấp hệ thống, giúp bảo vệ ứng dụng của bạn trước các mối đe dọa tương lai từ máy tính lượng tử trong thời gian ngắn nhất.
Researchers from Oak Ridge National Laboratory, Cleveland Clinic, and IBM have used quantum computers to calculate nine molecular configurations of FLiBe — a fluorine-lithium-beryllium molten salt critical for tritium fuel production in fusion reactors. This marks the first known instance of such computations on quantum hardware. The team applied quantum-centric supercomputing techniques — combining CPUs, GPUs, and QPUs — to determine electronic structure and tritium binding properties of FLiBe, a problem that is difficult to scale accurately on classical computers alone. The work is part of the DOE's Genesis Mission and builds on prior IBM quantum milestones including 12,635-atom protein simulations. The collaboration aims to scale molecular interaction modeling and eventually enable the fusion energy community to design and verify materials directly using this workflow.
Researchers from Kyushu University, the University of Waterloo, and Stockholm University have developed a theoretical framework called the 'Relativity of Spacetime Superpositions,' showing that many proposed experimental signatures of quantum gravity can alternatively be explained as quantum particles moving through a classical gravitational field. The framework does not rule out quantum gravity but highlights an important interpretive ambiguity, providing guidance for designing future experiments that could genuinely distinguish between classical and quantum descriptions of gravity.
IQM Quantum Computers has acquired selected software and IP assets from Quantistry GmbH, a Berlin-based developer of cloud-native simulation workflow software for industrial sectors including automotive, aerospace, chemicals, materials science, and pharmaceuticals. The deal brings Quantistry's simulation algorithms, ML/AI layer, and key technical staff into IQM's full-stack quantum platform. The acquisition coincides with IQM's Nasdaq listing via a business combination with Real Asset Acquisition Corp., making it the first European quantum computing company publicly listed on a major U.S. exchange. The combined platform aims to let enterprise R&D teams model molecular and physical properties using classical HPC, AI, and quantum backends within a single ecosystem.

France's cybersecurity agency ANSSI announced it will stop certifying security products that lack quantum-resistant encryption starting in 2027. Businesses are expected to purchase only quantum-safe products by 2030. Since ANSSI certification is mandatory for French government agencies and critical infrastructure, this policy effectively phases out older encryption standards across those sectors.
Silicon Quantum Computing (SQC) has appointed Karna Nisewaner as Chief Legal Officer, effective June 1, 2026. Nisewaner brings over 25 years of legal and executive experience from the semiconductor and AI industries, including senior roles at Cadence Design Systems, IBM, and Intuit. The hire supports SQC's commercial and governance strategy as it advances its silicon-based quantum computing roadmap. The appointment follows recent investments from Australia's National Reconstruction Fund Corporation and Firgun Ventures, and SQC's selection for Stage B of DARPA's Quantum Benchmarking Initiative.
MagiQware, a Netherlands-based startup, has raised €575,000 in pre-seed funding from Graduate Ventures, Delft Enterprises B.V., and LUMO Labs. The company develops AI-driven software targeting one of fault-tolerant quantum computing's biggest bottlenecks: magic state factories, which produce specialized quantum resources needed for error-corrected operations. Using reinforcement learning, MagiQware optimizes these factories dynamically within the quantum compiler stack, reporting up to a 40% reduction in circuit length in early results. The funding will support further development of software that reduces the resource overhead of quantum error correction, potentially making commercially viable quantum applications more practical.
EigenQ has announced post-quantum security capabilities compatible with Intel Xeon processor-based infrastructure, enabling organizations to achieve CNSA 2.0-aligned cryptographic readiness without replacing existing systems. The platform integrates post-quantum cryptography (PQC) and quantum entropy technologies with Intel's secure computing architecture to support sensitive workload protection, secure communications, identity, key generation, and attestation across federal, defense, space, and enterprise environments. BlackVe has also committed to using EigenQ's Intel-compatible PQC technologies as a foundational security layer for secure video systems in space and mission-critical applications.
