The world’s most sensitive table-top interferometric system—a miniature version of miles-long gravitational-wave detectors like LIGO—has completed its first science run.

The Quantum Enhanced Space-Time measurement (QUEST) experiment, based in Cardiff University’s School of Physics and Astronomy, aims to uncover the fundamental nature of space-time.

QUEST can measure changes in length 100 trillion times smaller than the width of a human hair and has set a new record for sensitivity in just a three-hour experiment.
