Physicists have built a device that allows them to measure the movement of single photons and could lead to advances in medical imaging and quantum computing.
Scientists closer to using ‘quantum light’ in medicine
Scientists are a step closer to harnessing quantum light energy to turbo charge medical imaging and bolster the power of supercomputers.
An international team of physicists, including Australians, have for the first time identified small numbers of photons - packets of light energy - interacting.
“This fundamental science opens the pathway for advances in quantum-enhanced measurement techniques and photonic quantum computing,” University of Sydney quantum optics expert Sahand Mahmoodian said.
The research team built a hyper-sensitive light-measuring device that allowed them to observe a single photon as it scattered off a quantum dot, which is a type of artificially created atom.
