A new Bar-Ilan University study points to a major advance in quantum information processing, demonstrating a way to send, manipulate, and measure quantum information across many frequency channels simultaneously, rather than one at a time. The study was recently published in the journal Science Advances.
The approach could allow quantum communication technologies, including secure key distribution and quantum teleportation, to operate far more efficiently by taking advantage of the enormous bandwidth already available in quantum light sources.
As Earth’s climate systems change, polar sea ice is becoming more granular in structure. University of Utah-led research reveals this type of ice is much less permeable than columnar sea ice, with important implications for geophysical processes. This is because water, heat and nutrients move less readily through granular ice than the ice it is replacing.
