Part of the lanthanide series, erbium (Er) is a rare-earth element found in a wide range of minerals like blomstrandine, polycrase, fergusonite, euxenite, xenotime, and gadolinite. C.G. Mosander ...

Qubits are the building block for quantum technology, and finding or building qubits that are stable and easily manipulated is one of the central goals of quantum technology research. Scientists have ...

Fiber lasers use an optical fiber doped with rare-earth elements (erbium, ytterbium, neodymium, etc.) as their optical gain source. They emit high-quality beams, they are efficient and durable, and ...

This week's element is erbium, which has the symbol Er and the atomic number 68. Erbium is another rare earths metal as its rhyming name alludes to. It was first isolated from minerals obtained from ...

Researchers in southern Germany made a novel optical resonator that they say looks ideal for the construction of quantum networks. The collaboration featuring the Max Planck Institute of Quantum ...

Scientists at the University of Chicago and partner institutions have demonstrated a new type of molecular qubit that operates at standard telecommunications wavelengths. The breakthrough could enable ...

Erbium is a lanthanide series rare-earth element (atomic number 68) characterized by a [Xe]4f¹²6s² electron configuration and prominent 4f–4f optical transitions that yield narrow emission lines, ...

Structural characterizations for the as-prepared catalysts. (a) XRD patterns of the Co3O4 and 4% Er−Co3O4. (b) Crystal structure of the Co3O4 in this study. (c) TEM image of 4% Er− Co3O4, (d-e) HRTEM ...
