To make an erbium atom function as such a quantum repeater, two main things need to go right. First, the atom needs to emit photons quickly enough to make the scheme practical. Second, the emitted ...

An erbium atom inserted into the lattice will communicate at a different frequency depending on the configuration of TiO 2 it sits in. In memQ's technique, ...

In a supercooled lab setting, a tiny crystal has quietly flipped a half-century-old assumption on its head. Scientists at ...

UNSW's Professor Sven Rogge said the technical feat was achieved with a single atom of erbium -- a rare earth element commonly used in communications -- embedded in silicon.

The spin state of a single erbium atom in a tiny silicon transistor has been probed using laser light. The finding opens a path towards a hybrid spin–photon quantum-computing architecture. See ...

Researchers were able to induce the phenomenon by applying a magnetic field — over 100,000 times stronger than the Earth’s — to a crystal made of erbium, iron and oxygen after cooling it to ...

When two ytterbium atoms absorb near-infrared photons, they can then transfer energy to a nearby erbium atom. In this excited state, the erbium can either decay directly to its lowest energy state by ...
