UrduScientists from Yale University and the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a systematic approach to understanding how energy is lost from the materials that make up qubits. Energy loss inhibits the performance of these quantum computer building blocks, so determining its sources — and adjusting the materials as necessary — can help bring researchers closer to designing quantum computers that could revolutionize several scientific fields.

Searching for the Decay of Nature’s Rarest Isotope: Tantalum-180m
The tantalum isotope, Ta-180m, is found naturally in a long-lived excited state. However, the radioactive decay of this excited state in Ta-180m has never been observed.
Direct View of Tantalum Oxidation that Impedes Qubit Coherence
Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory and DOE’s Pacific Northwest National Laboratory (PNNL) have used a combination of scanning transmission electron microscopy (STEM) and computational modeling to get a closer look and deeper understanding of tantalum oxide.
