Scientists have found a way to turn carbon dioxide and methane, the two most notorious greenhouse gases, into useful ...

Photons, for centuries both a puzzle and a tool, continue to help scientists illuminate nature at the smallest and largest ...

Researchers have uncovered a method to purify a photon stream that is central to quantum circuitry. University of Iowa ...

Physicists successfully teleport quantum information between photons from different sources, a key step towards a secure ...

A new approach to quantum light emitters generates a stream of circularly polarized single photons, or particles of light, that may be useful for a range of quantum information and communication ...

Quantum emitters work by releasing single photons, individual packets of light, on demand. This ability is critical because ...

Engineers at Stanford have created a new optical device that can easily manipulate light into basically any color desired. The system uses a series of modulators to fine-tune the frequencies of ...

Light, whether from a star or your flashlight, travels at 186,000 miles per second. Artur Debat/Moment via Getty Images My telescope, set up for astrophotography in my light-polluted San Diego ...

Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons.

I guess it's like how we use the square root of minus one to solve various equations. It sounda impossible but actually works! Click to expand... Sort've, but I don't think they're going into the ...
