Studying sources of energy loss to make quantum computing gains
Scientists at the Center for Functional Nanomaterials used transmission electron microscopy to analyze the elemental makeup of materials comprising quantum devices. The above image shows that there is no oxide…
Neutrons reveal the existence of local symmetry breaking in a Weyl semimetal
At higher temperatures (left), the Weyl semimetal lattice maintains its symmetry. At lower temperatures (right), local symmetry breaks down, as depicted by the atomic shifts and lattice distortions, which alters…
Study unveils limits on the extent to which quantum errors can be ‘undone’ in large systems
Credit: Quek et al. Quantum computers have the potential of outperforming conventional computers on some practically relevant information processing problems, possibly even in machine learning and optimization. Yet their large-scale…
