An imaging technique combining spectroscopy with high-resolution microscopy to produce rapid, precise measurements of quantum behavior in an atomic clock has been developed. Physicists believe the technique could improve atomic clock precision and provide a path toward measuring many-body interactions and testing fundamental physics. This is artwork made with JILA’s new imaging technique, which rapidly and precisely measures quantum behavior in an atomic clock. The images are false-color representations of atoms detected in the ground state (blue) or excited state (red). The white...Read full articleRelated content from Photonics MediaARTICLESOptical Clock Uses Laser Tweezers to Manipulate AtomsJILA physicists have demonstrated a new atomic clock design that uses laser tweezers to trap, control, and isolate atoms.
