Synthesize Impossible Superconductor

Authors: George Rajna

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. [30] Hong Ding's group from the Institute of Physics, Chinese Academy of Science reported the superconducting gap of topological surface state is larger than that of bulk states in β-Bi2Pd thin films using in-situ angle-resolved photoemission spectroscopy and molecular beam epitaxy. [29] Superconducting quantum microwave circuits can function as qubits, the building blocks of a future quantum computer. [28] Physicists have shown that superconducting circuits—circuits that have zero electrical resistance—can function as piston-like mechanical quantum engines. The new perspective may help researchers design quantum computers and other devices with improved efficiencies. [27]
