QAI Ventures Selects Four Startups for Singapore Quantum Accelerator Program

MySQL Community Server 26.7 Early Access Release

MySQL 26.7 Early Access is the first Innovation release after MySQL 9.7 LTS, adopting a CalVer yy.mm versioning scheme. Key highlights include: more robust InnoDB undo log truncation using a header flag instead of a local file; internal InnoDB recovery and metadata infrastructure improvements (redo log, tablespace, MVCC/ReadView interfaces); a new Change Stream Applier for parallel replication with separate apply and commit progression, configurable via APPLIER_VERSION=2; Group Replication now defaults to the MYSQL communication stack with deprecation warnings for XCom options; post-quantum cryptography support (ML-KEM hybrid and pure algorithms) when built with OpenSSL 3.5+; upgrade/compatibility check progress reporting; and the Thread Pool Plugin now available in Community Server. The release is for evaluation only and not intended for production use.

QUDORA Partners with QAI to Bring Ion-Trap Quantum Computing to South Korea

QUDORA Technologies, a European ion-trap quantum computing company, has signed a Memorandum of Understanding with South Korean quantum AI firm QAI Co., Ltd. The partnership will begin with a feasibility study on deploying QUDORA's ion-trap quantum computer within QAI's AI data center infrastructure in Korea. The collaboration aims to develop hybrid AI-quantum workflows, support customer education and technology demonstrations, and expand across major Asian markets including Japan, Vietnam, India, and Southeast Asia. QUDORA will lead system construction and technical integration, while QAI handles local market development and feasibility assessment.

Diraq Demonstrates Scaled Foundry-Fabricated Silicon-Based Qubit Array Made at imec

Diraq has successfully operated an eight-qubit silicon spin-qubit array fabricated using a standard 300 mm CMOS semiconductor manufacturing process, published in Nature Communications. This represents a fourfold increase from their previous two-qubit demonstration, achieved without degrading coherence or control performance. The qubits were fabricated by imec using the same industry-standard process from Diraq's 2025 Nature breakthrough. The readout architecture scaled favorably without significant increases in sensor count, wiring density, or thermal load. Diraq's roadmap targets hundreds of qubits currently, thousands by 2029, and over one million by 2031, all using conventional semiconductor manufacturing infrastructure.

ETH Zurich Demonstrates Quantum Computer Architecture With Mechanical Working Memory

ETH Zurich researchers have demonstrated a novel quantum computer architecture that uses microscopic mechanical resonators as quantum working memory, separating computation from storage in a design analogous to classical CPU-and-RAM architecture. Superconducting qubits act as the processor, while mechanical vibrations store quantum states. Mechanical resonators offer advantages over electromagnetic memory: smaller size, higher density, multiple vibrational modes per resonator, and longer quantum state lifetimes. The team validated the architecture by successfully executing the Quantum Fourier Transform and a period-finding algorithm, proving the system supports programmable quantum computation. Scalability to larger qubit and resonator counts remains the next engineering challenge.

Eight-qubit operation of a 300 mm SiMOS foundry-fabricated device

Researchers demonstrate the tuning and coherent control of an eight-qubit linear array of silicon spin qubits fabricated using a 300 mm CMOS-compatible foundry process at imec. All eight qubits were successfully characterized as four double-dot pairs, achieving Ramsey dephasing times up to 41 μs and Hahn-echo coherence times up to 1.31 ms. A cascaded charge-sensing protocol enables high-fidelity readout of the central four qubits. A two-qubit CZ gate operation between adjacent qubits with low phase noise is also demonstrated. The results establish operational scalability of silicon spin qubit arrays beyond the two-qubit regime while maintaining state-of-the-art coherence metrics.

Millisecond coherence times in gigahertz-frequency mechanical oscillators

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.

White House Quantum Summit Exclusive: America’s Commitment to a Quantum Future

Hội nghị cấp cao của Nhà Trắng tập trung vào việc thúc đẩy thương mại hóa công nghệ lượng tử tại Mỹ, với cam kết đầu tư hơn 1 tỷ USD trong chương trình chip quốc gia, khởi động sáng kiến cảm biến trị giá hàng trăm triệu USD, và mục tiêu phát triển máy tính lượng tử vào năm 2028 thông qua cuộc thi phần cứng mở. Các bên tham gia coi lượng tử là công cụ bổ trợ chứ không thay thế tính toán cổ điển và AI, trong khi lĩnh vực cảm biến lượng tử có thể triển khai thực tế sớm hơn.

Lập trình viên nên đọc bài này để hiểu cách các công nghệ lượng tử đang được chính phủ Mỹ định hình như một chiến lược công nghiệp hóa, từ đó tìm hiểu cách ứng dụng trong các lĩnh vực như AI, sensor và hạ tầng mới, đồng thời cảnh giác về những thách thức kỹ thuật và chiến lược kinh doanh mới trong tương lai.
