QC Design has published a paper on arXiv introducing Plaquette, a hardware-aware software platform for designing and evaluating fault-tolerant quantum computers. Unlike conventional approaches that rely on simplified Pauli noise approximations, Plaquette takes actual hardware error models (Kraus operators, Hamiltonian-Lindblad dynamics, or experimentally reconstructed quantum channels) and compiles them into appropriate simulation representations. The framework supports four sampler classes including a new XPauli sampler for leakage and environment sectors, and near-Clifford samplers for coherent errors, scaling to tens of thousands of qubits. Validated against superconducting, neutral-atom, and trapped-ion hardware models, Plaquette demonstrates that Clifford-only simulation can be overly optimistic by more than an order of magnitude in logical error rate.

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.
Fraunhofer's INQUBATOR quantum computing consulting and testing center has opened an application period for industry partners to submit use cases by August 31, 2026. At least four selected projects will receive approximately 10 months of collaborative support, including access to quantum hardware from multiple international providers, tailored consulting, and commercialization planning. No prior quantum computing knowledge or proprietary hardware is required. The initiative is funded by the German Federal Ministry of Research, Technology and Space and currently has active use cases in medicine, cybersecurity, insurance, and automotive sectors.
QuTech has released Tuna-17, a 17-qubit superconducting quantum computer developed at TU Delft, now freely accessible worldwide via the Quantum Inspire cloud platform. It is the third processor in the Tuna family (following Tuna-5 and Tuna-9), featuring 24 tunable couplers, a universal gate set, and mid-circuit measurements to support quantum error correction experiments and advanced NISQ algorithms. Built across a fully European supply chain involving TNO, Orange Quantum Systems, Qblox, Delft Circuits, and QuantWare, Tuna-17 emphasizes open architecture and interoperability. The platform allows over 100,000 shots per job with no usage caps, automatic self-calibration, and continuous performance reporting. The team is already developing the next processor, Tuna-28.
Cambridge Innovation Capital (CIC) has appointed Dr Ilana Wisby, founding CEO of Oxford Quantum Circuits (OQC), as Entrepreneur in Residence. During her seven years at OQC, Wisby launched Europe's first Quantum Computing as a Service product, delivered 32-qubit systems into commercial data centers, achieved a 55x valuation increase, and raised over $100 million in funding. In her new role, she will work within CIC's deep tech team to explore real-world quantum computing applications and help translate scientific research into commercial ventures. CIC's EIR programme connects experienced deep tech executives with high-potential IP and founders to accelerate commercialization.
Google has launched two academic research funding calls under its Academic Research Awards program, each offering up to $100,000 in unrestricted grants to university professors worldwide. The first targets early fault-tolerant quantum computing, seeking algorithms that can deliver practical value on near-term systems with limited logical qubits, with applications in life sciences, climate science, and materials research. The second focuses on securing quantum computers themselves — not post-quantum cryptography, but protecting the classical-quantum interface from side-channel attacks, data leakage in multi-tenant cloud environments, and compiler-level vulnerabilities. Applications are open through August 7, with decisions expected by October 30.
Researchers achieved millisecond-scale phonon coherence times in gigahertz-frequency mechanical oscillators using micro-fabricated high-overtone bulk acoustic-wave resonators (μHBARs) made from crystalline quartz. By combining non-invasive Brillouin-based laser spectroscopy with materials analysis, they identified subsurface damage, lattice distortions, and elemental impurities at crystal surfaces as the dominant source of phonon decoherence. An optimized polishing process removed the compromised surface layer, yielding a tenfold reduction in surface losses and Q factors exceeding 247 million at 12 GHz, corresponding to phonon coherence times of 6.2 ms. The study confirms negligible dephasing in these devices and proposes a path toward coherence times beyond 100 ms, with applications in quantum transduction, quantum memories, and circuit quantum electrodynamics.
Florida Atlantic University has appointed Robert Loredo as executive director of its Center for Quantum Technologies. Loredo brings over 20 years of experience in advanced computing education and has trained more than 300 quantum computing ambassadors worldwide. Under his leadership, FAU will become the first Florida university to host a large-scale quantum computer on campus — a D-Wave Advantage2 system with over 4,400 qubits — and will connect to the Florida LambdaRail secure quantum network. The initiative focuses on quantum algorithm development, hybrid classical-quantum workflows, workforce training, and industry partnerships spanning logistics, materials science, AI, and simulation.
Diamond nitrogen-vacancy (NV) center technology is bifurcating into two commercial tracks in 2026: quantum sensing (already generating revenue) and quantum computing (still limited to single-digit to low-tens qubit counts). NV centers operate at room temperature, eliminating the need for dilution refrigerators or vacuum chambers, which enables deployment in hospitals and semiconductor fabs. Ten companies are profiled across computing (Quantum Brilliance, SaxonQ, XeedQ), sensing (Qnami, QuantumDiamonds, SBQuantum), materials supply (Element Six, Diatope), medical imaging (NVision), and precision timing (Adamant Quanta). Sensing applications are commercially proven — QuantumDiamonds raised €91M and has worked with nine of the ten largest chip manufacturers, NVision's POLARIS MRI system is deployed at Memorial Sloan Kettering, and SBQuantum launched a magnetometer into orbit. NV quantum computing remains early-stage with no demonstrated advantage over classical or superconducting systems, and scaling beyond a few dozen qubits remains an unsolved engineering challenge.
