Photons survive dif昀椀cult conditions The researchers cooled the circuit board with a SNI physicists have investigated whether and how long micro- semiconductor sample (chip in the center) to mil- wave photons survive under adverse conditions. They found li-Kelvin temperatures in order to investigate the properties of the photon storage devices. (Image: that special photon memories can be produced with su昀케cient J. Ungerer, Department of Physics, University of quality even in close proximity to oxides, which are widely used Basel) in semiconductor technology. The photon memories, known as resonators, can therefore be used as sensors for quantum e昀昀ects in semiconductor structures.
