New non-invasive technique offers window into the Quantum World by measuring atom density
Scientists at the Raman Research Institute (RRI), Bengaluru, have developed a novel, non-invasive technique to measure the local density of cold atoms in real time without significantly disturbing their quantum state - an advance that could accelerate progress in quantum computing, quantum sensing and precision measurement technologies. The method, known as Raman Driven Spin Noise Spectroscopy (RDSNS), overcomes key limitations of conventional atom-imaging techniques used in cold atom experimen...
