Scientists establish world’s first integrated quantum communication network

Scientists have established the world's first integrated quantum communication network, combining over 700 optical fibers on the ground with two ground-to-satellite links to achieve...

Machine learning could lop a year off technology design cycle

If everything moved 40,000 times faster, you could eat a fresh tomato three minutes after planting a seed. You could fly from New York to...

New AI tool can predict in seconds what a movie will be rated

Movie ratings can determine a movie’s appeal to consumers and the size of its potential audience. Thus, they have an impact on a film’s bottom...

Scientists make a great leap toward quantum internet

Scientists achieve sustained, high-fidelity quantum teleportation. A viable quantum internet—a network in which information stored in qubits is shared over long distances through entanglement—would transform...

Quadriplegic patient uses brain signals to feed himself with two robotic arms

For more than 30 years—following an accident in his teens—Robert "Buz" Chmielewski has been a quadriplegic with minimal movement and feeling in his hands...

Scientists find new way to improve glass for fiber optics

Rapid, accurate communication worldwide is possible via fiber optic cables, but as good as they are, they are not perfect. Now, researchers from Penn State...
