NASA demonstrates ‘ultra-cool’ quantum sensor for first time in space
NASA’s Cold Atom Lab, shown where it’s installed aboard the International Space Station, recently demonstrated the use of a tool called an atom interferometer that can precisely measure gravity and…
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…
