Entanglement

Researchers have demonstrated quantum entanglement on a small satellite orbiting Earth. The team developed a miniaturized device that produces pairs of photons that are inextricably linked, which could help launch a fast and secure quantum internet.

In quantum entanglement, particle links are thought to be fragile. But now, physicists have managed to produce hot clouds of trillions of entangled atoms, breaking quantity records and showing that entanglement isn’t as fragile as previously thought.

Physicists have harnessed the weird world of quantum physics to develop a “quantum radar” prototype. The system uses the quantum entanglement phenomenon to detect objects, and it could eventually outperform conventional radar in some circumstances.

Scientists have achieved quantum teleportation between two computer chips for the first time, sending information between them without being physically or electronically connected. The feat opens the door for quantum computers and quantum internet.

Quantum entanglement is an eerie concept that Einstein himself had trouble accepting, and yet it’s been experimentally demonstrated. To find out whether there are other variables, a new experiment provides the strongest evidence so far of quantum entanglement or a 12-billion year “conspiracy."

In a quantum network, information is passed instantly between nodes that have been entangled, and are unhackable since any unauthorized observation of the data will scramble it. Delft scientists have now overcome a hurdle to that technology, by generating quantum links faster than they deteriorate.

Chinese scientists claim to have launched the world's first quantum communications satellite with which they intend to experiment with quantum communication and teleportation from space, in the hope of one day producing an entire global network of quantum communication systems.

Incorporating a number of quantum technologies on a single integrated chip, an international team of researchers claim that their work paves the way for quantum computing circuits to be built into a range of everyday devices

Researchers have managed to entangle three photons and add a 3-D corkscrew motion that effectively allows multiple recipients to simultaneously receive information securely encoded in the one transmission

Scientists working at the University of Chicago and the Argonne National Laboratory claim to have entangled atomic nuclei at room temperature on a semiconductor chip, using the application of relatively small magnetic fields.

University of New South Wales scientists have for the first time created two entangled qubits in silicon with record fidelity, paving the way for reliable, massively scalable quantum computers.

Researchers working at the National Institute of Standards and Technology (NIST) claim to have teleported the quantum information carried in light particles over 100 km (62 miles) of optical fiber, four times farther than the previous record.
