The researchers showed that the time it takes for atoms to synchronize reveals information about how entangled the system is, potentially offering new ways to harness quantum properties for enhanced precision measurements.
To distinguish true gravitational effects from other influences like magnetic fields, the scientists developed a technique called dressing. By applying specific lasers, they could tune how strongly atoms experience gravitational time dilation, providing a clear signature that the effect truly comes from Einstein’s relativity rather than experimental artifacts.
