An atom in a cavity extracts highly pure single photons from weak laser light

Quantum physicists can now distil a kind of photon schnapps. When spirits are distilled, the alcohol content increases relative to the water content. A similar method developed by a team from the Max Planck Institute of Quantum ...

Mini-detectors for the gigantic? Bose-Einstein condensates are currently not able to detect gravitational waves

The gravitational waves created by black holes or neutron stars in the depths of space have been found to reach Earth. Their effects, however, are so small that they can only be observed using kilometer-long measurement facilities. ...

Spacetime—a creation of well-known actors?

Most physicists believe that the structure of spacetime is formed in an unknown way at the Planck scale, i.e., at a scale close to one trillionth of a trillionth of a metre. However, careful considerations undermine this ...
