WASHINGTON — Today’s quantum technologies rely on energy-intensive lasers, raising concerns that scaling them up could further increase energy demands. In new work, researchers have demonstrated that ...

For the first time, researchers in China have demonstrated how quantum dots can be engineered to consistently generate pairs of entangled photons. By carefully tailoring the photonic environment ...

Efficient generation and reliable distribution of quantum entangled states is crucial for emerging quantum applications, including quantum key distribution (QKDs). However, conventional ...

Quantum signals have now survived a rough ride through fiber-optic cable strung above Maryland streets. The achievement marks a serious step toward quantum networks that could someday link computers, ...

Using a new cone-shaped solar concentrator, researchers showed that sunlight can be used to create entangled photons. This could one day enable satellites to create secure encryption keys using the ...

Once cooled, the laser light has to give the bead a bit of a kick in just the right way to entangle the two. This is done by ...
