University of Iowa researchers have discovered a method to "purify" photons, an advance that could make optical quantum ...

University of Iowa researchers have modeled how to create more efficient, secure, and scalable quantum technologies through ...

A new experiment has demonstrated something that sounds physically impossible – light itself casting a shadow. It turns out that if you manipulate a laser just right, then hit it side-on with another ...

Dozens of times over the last decade NASA scientists have launched laser beams at a reflector the size of a paperback novel about 240,000 miles (385,000 kilometers) away from Earth. They announced ...

Using advanced computational modeling, a research team led by the University of Oxford, working in partnership with the Instituto Superior Técnico at the University of Lisbon, has achieved the ...

At any given moment, trillions of particles called neutrinos are streaming through our bodies and every material in our surroundings, without noticeable effect. Smaller than electrons and lighter than ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...

researchers at Colorado University Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The researchers say that the new ...
