An international team of researchers from Spain, Italy, France, Germany, and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by nuclear quantum fluctuations. Their result suggests that superconductivity approaching room temperature may be possible in hydrogen-rich compounds at much lower pressures than previously expected. The results are published today … Read more
When it comes to electronics, bigger usually isn’t better. This is especially true for a new generation of wearable communication systems that promise to connect people, machines and other objects in a wireless “internet of things.” To make the devices small and comfortable enough to wear, scientists need to miniaturize their components. Now, researchers in ACS … Read more
A scientific team from the Department of Energy’s Oak Ridge National Laboratory and Vanderbilt University has made the first experimental observation of a material phase that had been predicted but never seen. The newly discovered phase couples with a known phase to enable unique control over material properties – an advance that paves the way … Read more
Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have new experimental evidence and a predictive theory that solves a long-standing materials science mystery: why certain crystalline materials shrink when heated. Their work, just published in Science Advances, could have widespread application for matching material properties to specific applications in medicine, electronics, and other fields, … Read more
Last year, graphene made another major splash in the headlines when scientists discovered that by simply rotating two layers of this material one on top of the other, it could behave like a superconductor where electrical currents can flow without resistance. This new phase of matter was seen to appear only when the two graphene … Read more
Researchers from the U.S., Russia, and China have bent the rules of classical chemistry and synthesized a “forbidden” compound of cerium and hydrogen – CeH9 – which exhibits superconductivity at a relatively low pressure of 1 million atmospheres. The paper came out in Nature Communications. Superconductors are materials capable of conducting an electric current with no resistance … Read more
A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, “non-Gaussian” noise processes that are routinely encountered in superconducting quantum computing systems. The characterization of non-Gaussian noise in superconducting quantum bits is a critical step toward making these systems more precise. … Read more
A team of scientists has collected experimental evidence indicating that a large concentration of electron pairs forms in a copper-oxide (cuprate) material at a much higher temperature than the “critical” one (Tc) at which it becomes superconducting, or able to conduct electricity without energy loss. They also detected these pairs way above the superconducting energy … Read more
Scientists, mainly from Zhejiang University led by Professor Haohua Wang and Institute of Physics of Chinese Academy of Sciences led by Professors Heng Fan and Dongning Zheng, have successfully created Schrödinger cat states of up to 20 qubits with a superconducting quantum processor. In addition, they show that the generated 18-qubit Greenberger-Horne-Zeilinger (GHZ) state is … Read more
A potentially useful material for building quantum computers has been unearthed at the National Institute of Standards and Technology (NIST), whose scientists have found a superconductor that could sidestep one of the primary obstacles standing in the way of effective quantum logic circuits. Newly discovered properties in the compound uranium ditelluride, or UTe2, show that … Read more
