Sentences with phrase «as ytterbium»

These crystals are doped with elements such as ytterbium, gadolinium, erbium, and thulium, which emit visible colors when exposed to near - infrared light.

Not exact matches

Efforts to improve the intensity of these emissions have focused on ytterbium (Yb) rare - earth dopants, as they are easily excitable with standard lasers.

To that end the researchers utilized a pair of ytterbium ions as quantum bits, or qubits, each confined to a private vacuum chamber about a meter apart in an experimental system at the Joint Quantum Institute of the University of Maryland and the National Institute of Standards and Technology.

But there is a catch: the ytterbium clock is still not as accurate as the caesium one.

Little is rarer than an observable quantum spin liquid, but now, tests reveal that a synthetic crystal with ytterbium as its base may house one at near absolute zero.
