Erbium atoms in silicon: A prime candidate for quantum networks

A team of researchers at the MPQ has pioneered the integration of erbium atoms with special optical properties into a silicon crystal. The atoms can thus be connected by light at a wavelength that is commonly used in telecommunications. ...

Chaining atoms together yields quantum storage

Engineers at Caltech have developed an approach for quantum storage that could help pave the way for the development of large-scale optical quantum networks.
