Ting Rei Tan talks quantum clocks — and why atomic ones are so much more precise than the pendulums in a grandfather clock (or even the crystal in a quartz watch).
Ting Rei is an Associate Professor at the University of Sydney working at the intersection of atomic physics and quantum computing. He explains how atomic clocks work, why GPS depends on them being extraordinarily precise, and how the whole global timekeeping system quietly outsources itself to a network of atomic clocks most of us never think about. Along the way: the case for lutetium over cesium, and what it would mean to measure quantum gravity itself.

What is Clear as Quantum?
Clear as Quantum is an EQUS podcast about quantum science and the exciting technologies that are getting ready to unleash a quantum revolution. In this “spooky podcast at a distance” we’ll try to dust the cobwebs out of the quantum physics realm that's entangling our lives. Over the course of 10 episodes you’ll hear from some of Australia’s leading quantum scientists, and learn things worth knowing about.
