We have created a gas of photons that can be extremely compressed, confirming the predictions of quantum theory. The findings could also point the way to new types of sensors that can measure minute forces. The study is published in the journal Science.

Researchers at the University of Bonn have created a gas of light particles that can be extremely compressed. Their results confirm the predictions of central theories of quantum physics. The findings could also point the way to new types of sensors that can measure minute forces. The study is published in the journal Science.
