Researchers at the National Institute of Standards and Technology (NIST), Massachusetts Institute of Technology (MIT) and the Perimeter Institute recently set new constraints on dark photons, which are hypothetical particles ...
A team of physicists at the University of Edinburgh's School of Physics and Astronomy has used mathematical calculations to show that quantum communications across interstellar space should be possible. In their paper published ...
It may seem like technology advances year after year, as if by magic. But behind every incremental improvement and breakthrough revolution is a team of scientists and engineers hard at work.
