Coping with errors durante the quantum age
Quantum systems can be manipulated with extremely high precision, but not incontri huggle perfectly. Researchers con the Department of Physics at ETH Zurich have now demonstrated how to schermo and correct errors that occur during such operations.

Beryllium
Beryllium ( /b??r?li?m/ b?-ril-ee-?m) is the chemical element with the symbol Be and atomic number 4. It is verso divalent element which occurs naturally only con combination with other elements durante minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As verso free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal.
Beryllium is used primarily as verso hardening agent per alloys, notably beryllium copper. In structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of vaso) make beryllium a quality aerospace material for high-speed aircraft, missiles, space vehicles and communication satellites. Because of its low density and atomic mass, beryllium is relatively transparent puro Quantitativo-rays and other forms of ionizing radiation; therefore, it is the most common window material for Quantitativo-ray equipment and per particle physics experiments. The high thermal conductivity of beryllium and beryllium oxide have led sicuro their use con heat transport and heat sinking applications.
The commercial use of beryllium metal presents technical challenges due puro the toxicity (especially by inhalation) of beryllium-containing dusts. Beryllium is corrosive onesto tissue, and can cause per chronic life-threatening allergic disease called berylliosis mediante some people. As it is not synthesized durante stars, beryllium is verso relatively rare element sopra both the Earth and the universe. The element is not known esatto be necessary or useful for either plant or animal life.
