Non-invasive way to feel density of atoms can provide a new window into the Quantum World

• Raman Driven Spin Noise Spectroscopy (RDSNS) — a new technique to measure the local density of cold atoms in real time without destroying them, developed at Raman Research Institute (RRI), Bengaluru.
• Replaces destructive absorption/fluorescence imaging used in cold-atom quantum experiments.
• Relevance: directly feeds into National Quantum Mission deliverables — quantum computing, quantum sensing, gravimeters, magnetometers.
