A quantum network of entangled atomic clocks
Scientists at the University of Oxford have been able to demonstrate a network of two entangled optical atomic clocks and show how the entanglement between the remote clocks can be used to improve their measurement precision.

Super accurate clocks have got practical uses, one application that might be possible in the future is a gravity sensor. So put the clock in a satellite and underground mineral deposits could be detected from space. Now you don't need the clock to be quatum entangled for this to work, but I wonder what a network of super accurate clocks linked together could do?
