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 ...

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 ...

A laser fired at a sheet of titanium dioxide changes the configuration of the crystal where it hits – a technique, developed by the quantum startup memQ, that enables scientists to design a more ...

The quantum computer has the potential to revolutionize the 21st century, solving problems so massively complex they would baffle today’s computers. But a single quantum computer is still no match for ...

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 ...

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 ...

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, ...
