Physicists developed a method to create and control quantum superpositions in the motion of a trapped strontium ion, turning the ion's internal spin into a tool to sculpt cat-like quantum states with distinctive interference patterns, expanding the Schrödinger cat family and offering new capabilities for quantum computing, simulations, and sensing.
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.
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.
A cryogenic device generates tunable, predictable phonons (quantized sound) by driving electrons through a 2D crystal, offering a new route for quantum communications—particularly where light struggles, like the deep ocean—though it requires ultracold temperatures to work.
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.
Scientists at Florida State University have created a new crystalline material with complex swirling magnetic patterns called skyrmion-like spin textures, achieved by combining similar compounds with different crystal symmetries, which could advance data storage and quantum computing technologies.
