According to a video shared on YouTube, a bright beam of light shone down on the pass ... or tinkering with something on his computer.

Scientists in Florence have built a device that allows them to study quantum and classical physics side by side. Using ...

Researchers at the University of Ottawa have found that using helical light beams in disordered solids reveals this dichroism. This discovery contradicts prior beliefs and provides an opportunity ...

When the results of one beam's measurements are subtracted from the other, signals which would be hidden by shot noise in classical light are revealed, enabling more sensitive measurements.
