Researchers from the Nägerl group and collaborators have demonstrated that a one-dimensional gas of ultracold cesium atoms can be driven into a novel non-equilibrium quantum state called a 'fractional Fermi sea.' By cyclically switching particle interactions between strongly repulsive and strongly attractive regimes, the atoms reorganize into a highly excited yet highly ordered many-body state rather than simply heating up. This state exhibits distinct correlation patterns — including Friedel oscillations — that differ from the established Tomonaga-Luttinger liquid model, suggesting an entirely new exotic critical phase of matter. The findings open new pathways for quantum simulation beyond known equilibrium paradigms, with the experimental realization paper still under review.

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.

STMicroelectronics has launched the ST54M, a single-die secure mobile chip integrating post-quantum cryptography (PQC) hardware acceleration, NFC, secure element, and eSIM functionality. The chip supports PQC algorithms ML-KEM and ML-DSA, and is designed to help OEMs meet anticipated quantum-ready security mandates expected around 2030. It targets applications like contactless payments, digital identity, transit ticketing, and digital car keys. The ST54M has completed Common Criteria EUCC and EMVCo certification testing, includes up to 4.5 MB nonvolatile memory, and is available for sampling with production expected in July 2026.
Yale's ERASE project has received a $4 million NSF grant to fund a two-year second phase focused on developing a blueprint for a large-scale, error-correcting quantum computer. The project centers on erasure qubits — dual-resonator quantum bits that can flag dominant errors as they occur, simplifying error correction. Partners include D-Wave Quantum (which acquired Yale spin-off Quantum Circuits Inc.), Princeton, the University of Maryland, and Southern Connecticut State University. The phase will expand research, software, algorithm development, and quantum workforce training in Connecticut, with a detailed hardware plan for a future Phase 3.
The University of Maryland is funding a research project combining quantum computing and machine learning to accelerate the discovery of single-atom catalysts for cancer detection and treatment. Part of the university's Grand Challenges Grants Program, the project brings together engineers and computer scientists to build a predictive framework that models complex atomic and chemical behaviors — tasks difficult for classical computers. Quantum simulations would generate reliable databases of electronic structures and catalytic pathways, which machine learning models would then search to identify promising catalyst configurations. The team also plans to release benchmark datasets and reproducible computational tools to support open science. The research is preclinical and focused on discovery, not immediate clinical application.
A comprehensive overview of the leading quantum computing investors in 2026, covering dedicated quantum VC funds (Quantonation, 55 North, Firgun Ventures), corporate venture arms (Google Ventures, IBM Ventures, Microsoft M12, Amazon), sovereign wealth funds (Temasek, Mubadala), and government-backed programs (In-Q-Tel, SGInnovate, HTGF). Private VC in quantum reached $4.9 billion in 2025, more than doubling the prior year. The piece profiles each investor's focus, confirmed portfolio companies, preferred funding stage, and geographic orientation. It also covers how to pitch quantum investors, key metrics they evaluate (qubit count, gate fidelity, coherence times, commercialization roadmap), typical funding amounts by stage, and the complementary roles of government grants versus venture capital for quantum startups.
Taiyi Quantum, a six-month-old Shanghai-based startup, has raised 300 million yuan (~$44M USD) in a Pre-A funding round led by Gaorong Venture Capital and IDG Capital. The company is led by Liu Hongbin, a former Microsoft Azure Quantum Principal Architect who worked on Microsoft's neutral-atom initiative with Atom Computing. Taiyi is developing a ytterbium-based neutral-atom quantum computer, leveraging laser-trapped atoms as qubits. Ytterbium offers advantages including stable nuclear-spin qubit states, precise laser control, and reduced noise compared to alkali atoms like rubidium or cesium. The large raise for such a young startup signals growing investor confidence in China's quantum computing sector.
Researchers demonstrate spin–electric coupling (SEC) in two molecular spin systems—iron phthalocyanine (FePc) and Fe–FePc complexes—on MgO/Ag(001) surfaces using electron spin resonance combined with scanning tunnelling microscopy (ESR–STM). By varying the DC bias voltage, they observe a strongly nonlinear resonance frequency shift reaching up to ~30%, far exceeding previous reports. This nonlinear behavior is attributed to a transport-mediated exchange interaction (exchange bias) between the magnetic STM tip and the molecular spin, linked to the energetic position of the molecular LUMO. The mechanism is validated by full transport simulations and DFT calculations. The team further demonstrates all-electrical coherent spin control via Rabi oscillation measurements on single and coupled Fe–FePc dimers, showing that individual spins can be selectively detuned using only DC voltage. This exchange bias mechanism is highly localized, broadly applicable, and opens a pathway toward electrically controlled quantum gate operations in molecular spin assemblies.
