  • The exceptional quality of hexagonal boron nitride crystals that can be cleaved into few layers provides ultrathin dielectrics, thereby opening a route to ultrasmall capacitors with large capacitances. With such capacitors, the superconducting transmon qubit is scaled down by orders of magnitude.

  • Glass-forming ability in metallic systems is related to the diversity of atomic packing schemes quenched into the glassy state, which manifests itself in the width of the first broad X-ray diffraction peak. This provides a swift way for screening libraries of deposited alloy films and searching for good glass formers.
