An international team of physicists has uncovered a subtle but important twist in how “memory” works in quantum systems.

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 ...

Researchers in the US have demonstrated how quantum entanglement could be used to detect optical signals from astronomical ...

Preserving quantum information is key to developing useful quantum computing systems. But interacting quantum systems are chaotic and follow laws of thermodynamics, eventually leading to information ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists demonstrated quantum teleportation over fiber-optic cables carrying live internet data, opening a path to real-world ...

A new room-temperature quantum device developed at Stanford uses twisted light and advanced materials to link photons and ...

The parity-identification problem fits naturally into this landscape. Parity is a global property, insensitive to most local details. In this respect, it resembles many other quantities studied in ...

Scientists built a quantum gate linking four-state photons, showing complex quantum tasks can be done with fewer steps using qudits.

Crystal jellyfish have an eerie beauty: thanks to a natural protein, they emit a faint green glow. For decades, researchers ...

In the 1971 film Willy Wonka & the Chocolate Factory, Willy Wonka teleports a larger-than-life candy bar (and a small child) across the room into a television set. The idea of instantly transporting ...
