The short version
- However, it requires single photons—and generating them is very difficult.
- Researchers at the Technical University of Munich (TUM) and the Munich Center for Quantum Science and Technology (MCQST) have developed a new method that overcomes the problems of previous approaches.

What happened
Editors have highlighted the following attributes while ensuring the content's credibility: Quantum communication promises many advantages over today's standard technologies, including absolutely secure transmission of large amounts of data. Instead of amplifying the desired frequency, the researchers selectively suppress unwanted frequencies.
Why it matters
Until now, so-called resonators have mostly been used to produce single photons—tiny optical structures that influence photon sources, causing them to emit light predominantly at a specific frequency.
