Physicists reach atomic-scale telegraphy with light

In the 1880s Heinrich Hertz discovered that a spark jumping between two pieces of metal emits a flash of light—rapidly oscillating electromagnetic waves—which can be picked up by an antenna. To honor his groundbreaking ...

Tracking the dynamics of biomolecules with optofluidic antennas

In order to better understand fundamental processes in life science at the molecular level, the precise observation of single molecule dynamics is of utmost interest. However, current techniques based on fluorescence measurements ...

Unveiling a new quantum frontier: Frequency-domain entanglement

Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has ...
