The Qube research satellite to test quantum key distribution launched ... and more efficient power consumption. In this way, laser stands well apart from QKD and any other technology.

Researchers working with the U.S. Defense Advanced Research Projects Agency (DARPA) have been awarded a $1 million grant to ...

Two quantum information theorists have solved a decades-old problem that will free up quantum computing power.

The discovery, centred around controlling tiny hurricanes of light and electromagnetic fields, could revolutionise how much information we can deliver over cables.

Quantum computers would be especially useful for cryptography as well as discovering new types of pharmaceutical ... In 2017 researchers at the University of Science and Technology of China used ...

The V-score ("V" for "Variational Accuracy") offers a consistent way to compare how well different quantum methods perform on the same problem. The V-score can be used to identify the hardest-to ...

Quantum entanglement is one seriously long-distance ... In addition to proving Bell's Theorem, there are practical applications to this work as well. The "superconducting nanowire single-photon ...

Neutral atoms are used for analog quantum simulations ... Additionally, they interact well with other Rydberg atoms and can be easily manipulated using laser fields. In the context of the Nature ...

Quantum dots could revolutionize medicine. Unfortunately, most of them are toxic. Ironically, the existence of heavy metals in QDs such as cadmium, a well-established human toxicant and carcinogen, ...
