US-Sweden Forge Broad Tech Prosperity Pact to Accelerate AI, Quantum, and Space

The United States and Sweden signed a non-binding Memorandum of Understanding to deepen bilateral collaboration across AI, secure connectivity, biomedical research, manufacturing, energy, space, defense, quantum tech, and research-security. A Joint Committee will oversee implementation, with activities to be defined in future agreements and within applicable laws; no funds are committed at this stage, and IP or data-sharing terms will be set in separate arrangements.

Picometer-precision atom steering yields mesoscopic defect crystal in CrSBr

Researchers demonstrate deterministic atomic engineering inside CrSBr by steering Cr atoms with sub-20-pm accuracy to create a mesoscopic 3D defect crystal (~40,000 defects) within a 150×100×13 nm volume. The engineered lattice is stable at room temperature and opens routes for deterministic colour-centre placement, quantum simulations of many-body systems, and scalable atomic-scale manufacturing outside the microscope.

Birth of quantum entanglement captured in attoseconds

Researchers directly measured the birth of quantum entanglement on attosecond timescales by exciting atoms with intense laser pulses, showing the departure timing of one electron is linked to the energy state of the remaining electron (roughly 232 attoseconds on average). They developed a two-laser measurement protocol to capture this ultrafast entanglement, with potential implications for quantum technologies and communications.
