Coherent control of an artificial atom with few photons

In an optical quantum network, the information is transferred from one node to an other through light. A possible building block for such quantum network is an atom in a cavity. Ideally, every photon sent on the node should interact with the atom. Researchers at C2N, in collaboration with Institut Néel (Grenoble, France) have demonstrated the coherent control of an artificial atom with few photons. The quantum node …

Flexible nitride nanowires light emitting diodes

Presently, flexible light sources mainly use organic materials integrated on lightweight and flexible plastic substrates. However, organic LEDs present a much lower luminance and a shorter lifetime in comparison to the LEDs based on inorganic nitride semiconductors. The inorganic semiconductor devices in their bulk form are mechanically rigid. Polymer-embedded nanowires (NWs) offer an elegant solution to create flexible optoelectronic devices, which combine the high efficiency and the long lifetime …
