The graviton - the quantum particle of gravity
Igor Pikovski has been interviewed by Swedish Radio about how they will use a small supercold resonance box and quantum sensor technology to detect gravitons. They believe that gravitons can be detected using quantum sensor technology. These particles have previously been considered impossible to observe. Igor Pikovski is a senior lecturer at the Department of Physics.
Researchers in Stockholm propose in Nature Communications a way to detect the tiny particle graviton, which is theorised to exist as the smallest component of gravity. Igor Pikovski at Fysikum, Stockholm University, proposes a small supercold resonance box.
"Finding the graviton is so difficult that no one has tried before," says physics professor Ulf Danielsson, Uppsala University.

There should be a quantum particle that belongs to gravity. Now researchers in Stockholm are proposing a way to find it. If they succeed, it will be a step towards the answer to the biggest question in physics.
