Researchers at DOE’s ORNL and collaborators realize quantum communications milestone using light

A team of researchers at the Department of Energy’s Oak Ridge National Laboratory, along with external collaborators, has taken an important step toward developing efficient quantum communications networks that connect quantum devices while preserving the delicate states of the particles used to transmit information by harnessing the frequency, or color, of light. Such capabilities could contribute to more practical and large-scale quantum networks exponentially more powerful and secure than the classical networks we have today.

Specifically, the team is harnessing the properties of light and the principles of quantum mechanics to transfer information, making the network itself a photonic quantum information processor. This approach is promising for several reasons. To learn more click here.
