Webster's Revised Unabridged Dictionary
    • n Erbium (Chem) A rare earth element of the lanthanide series associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. Symbol Er. It has atomic number 68 and an atomic weight of 167.26. The pure element is metallic with a bright, silvery luster. It is relatively stable in air, not oxidizing as quickly as some other rare earths. Its salts are rose-colored and give characteristic spectra, and the pink oxide has been added as a colorant in glass and porcelain enamel glazes. Its sesquioxide Er2O3 is called erbia.

    • n erbium Chemical symbol, Er; A rare metal found along with yttrium, terbium, and a number of other rare elements in some rare minerals, as euxenite, fergusonite, and gadolinite, in which it exists as a tantalate or silicate.

Octave Spanning Frequency Comb on a Chip
The experimental setup for octave spanning frequency comb generation in a toroidal microresonator is depicted in Figure 1a and consists of an external cavity diode laser (ECDL) that is amplified by an erbium doped fibre amplifier (EDFA) to an output power of up to 2.5 W.

Universal cloning (first column), which clones all possible qubits with equal fidelity, can be realized with a simple optical amplifier, e.g. an erbium doped fiber amplifier .
Cloning Entangled Qubits to Scales One Can See
Universal cloning necessarily comes with additional quantum systems, called anti-clones; in the mentioned example the additional systems are the erbium ions.
