Up front:Atomic clocks have been in popular use since the 1950s.
The Oxford teams experiment involved a relatively new wrinkle to the formula called an optical atomic clock.
This allows scientists to make more robust measurements.
But entangled clocks are, theoretically, capable of much greater accuracy.
Quick take:The potential implications for this research are humongous.
And, best of all, theres not much downside to pursuing this research.
