Wiring up quantum circuits with light

Quantum computers promise to solve challenging tasks in material science and cryptography that will remain out of reach even for the most powerful conventional supercomputers in the future. Yet, this will likely require millions ...

Team manages to dynamically control trions with a waveguide

Things do not always go as one wants in reality. This is especially true in the world of light. However, a research team at POSTECH has successfully controlled "trions," a breakthrough toward developing what could ultimately ...

ESO telescope reveals hidden views of vast stellar nurseries

Using ESO's Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics ...

Communication is the activity of conveying meaningful information. Communication requires a sender, a message, and an intended recipient, although the receiver need not be present or aware of the sender's intent to communicate at the time of communication; thus communication can occur across vast distances in time and space.
