A new paper introduces a novel way to observe very delicate bodies based on quantum physics. Researchers in Spain have shown that groups of photons organized in certain quantum states can gently explore the properties of objects in a non-invasive way. The results overcome for the first time a limit imposed by quantum mechanics, and may permit the observation of unknown properties of ultra-sensitive objects such as individual atoms or living cells.
