Researchers at Delft University of Technology have successfully observed real-time switching of the nuclear spin in a single atom using a scanning tunneling microscope, achieving single-shot readout and revealing potential for advanced quantum control and sensing at the atomic level.
Scientists have successfully detected the X-ray signature of a single atom for the first time using synchrotron X-ray scanning tunneling microscopy (SX-STM), opening new possibilities in environmental, medical, and quantum research. The team was able to identify and characterize individual atoms, which could revolutionize the way scientists detect materials. The smallest amount one can X-ray a sample is in attogram, that is about 10,000 atoms or more, due to the X-ray signal produced by an atom being extremely weak so that the conventional X-ray detectors cannot be used to detect it.
Scientists from Ohio University, Argonne National Laboratory, and the University of Illinois-Chicago have taken the world's first X-ray signature of a single atom using synchrotron X-ray scanning tunneling microscopy. The team used a specialized detector made of a sharp metal tip positioned at extreme proximity to the sample to collect X-ray excited electrons. The technique could revolutionize research and give birth to new technologies in areas such as quantum information and the detection of trace elements in environmental and medical research.
