Examples of thulium
thulium
Words like yttrium, holmium, lanthanum, and thulium don't exactly roll off the tongue.

Tittel's team started by channelling one photon of an entangled pair into a crystal of lithium niobate doped with ions of thulium.

Beforehand, the team strategically removed some thulium ions, leaving only those that absorb a particular sequence of frequencies.

Then there's holmium from Stockholm, thulium from Thule, and gadolinium, after the industrious Finnish element hunter Johan Gadolin.

Since the internal contrast is too difficult to measure, external agents such thulium compounds are used to enhance the effect.

This sends the crystal into a quantum superposition, in which many thulium ions absorb the photon at once and vibrate at different frequencies.

- Thulium is a chemical element that has the symbol Tm and atomic number 69. Thulium is the least abundant of the lanthanides (promethium is less abundant than thulium, but it is not found naturally on Earth). It is an easily workable metal with a bright silvery-gray luster. ...
- A metallic chemical element (symbol Tm) with an atomic number of 69
- T-M. For more information on this and other elements, see The elements. And for fun, listen to Tom Lehrer singing the "Song of the elements" at Flashimation.
