A new molecule developed by Ohio State University scientists can harvest energy from the entire visible spectrum of light, harnessing up to 50 percent more solar energy than current solar cells, and can also catalyze that energy into hydrogen.
-
In a new distance record, researchers have sent a photon, entangled with an ion, down a 50-km (31-mi) long optical fiber.

Scientists from Austria and China throw Schrodinger's Cat for a loop.

Astronomers have now asked “how much light has been emitted in the universe?” Using a new measurement method, the team has apparently managed to quantify all the starlight ever produced in the observable universe – and the result is a figure that’ll make your eyes water.

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."

Photons, the elementary particles that make up light, are fast, weightless and don't interact with each other. But in new experiments, physicists have now created a new form of light, demonstrating that groups of photons can be made to interact with each other, slow down and gain mass.

Researchers at Caltech have developed a computer chip that can store quantum information in the form of light, at the nanoscale. The breakthrough is the latest step towards quantum computers and networks, which would allow information to be processed and transmitted faster and with smaller devices.

Keeping tabs on where a medical scope is when inside a human body often relies on expensive imaging technologies. A team at the University of Edinburgh has now developed a camera that can detect traces of light from the tip of an endoscope through up to 20 cm (7.8 in ) of tissue.

Quantum encryption could make for much less hackable communication networks. But for it to really take off it needs to work out in the real world, among other signals and natural air turbulence. Now, researchers have successfully sent a message with 4D quantum encryption between two rooftops.

Even in the bizarre world of quantum physics there are some behaviors researchers felt they could count on – such as the way entangled photons operate. But new research has shown that even those tiny particles of light don't behave as we previously thought.
-
In one more step on the road to a functional quantum computer, researchers at Harvard University and Sandia Ion Beam Laboratory claim to have created the very first "bridge" that could effectively link strings of quantum computers together in a single networked unit.

ScienceRemember when Kylo Ren used the Force to stop a laser blast in mid-air? In a Canberra laboratory, physicists have managed a feat almost as magical: they froze the movement of light in a cloud of ultracold atoms. This discovery could help bring optical quantum computer from sci-fi to reality.
