Slowing light in an optical cavity with mechanical resonators and mirrors

Theoretical physicists have shown how a position-dependent mass optomechanical system involving a cavity between two mirrors, one attached to a resonator, can enhance induced transparency and reduce the speed of light.

Zeptoseconds: New world record in short time measurement

Atomic physicists have for the first time measured how long it takes for a photon to cross a hydrogen molecule: about 247 zeptoseconds for the average bond length of the molecule. This is the shortest timespan that has been successfully measured to date.

Building a microscope with quantum light

Researchers have built the first infrared based microscope with quantum light. By deliberately entangling the photons, they succeeded in imaging tissue samples with previously invisible bio-features.
