N2 - Over the last year, the world has seen significant progress in studies of ultracold atoms and their applications. Researchers have produced optical frequency standards based on forbidden transitions of atoms and ions with record high metrological parameters (better than 10-18 in terms of relative stability and uncertainty), made impressive advances in the spectroscopy of cold antihydrogen atoms, demonstrated laser spectroscopy of ultracold multiply charged ions, significantly improved the performance of quantum sensors (gyroscopes, accelerometers and gravimeters) based on matter waves of ultracold atoms and implemented quantum registers based on atoms and ions with a number of qubits approaching 100 and more.
