Engineering a quantum frontier for atomic clocks and fundamental physics

Scaling up the size of coherent quantum systems advances the frontier of precision measurement, and quantum entanglement is poised to make major impact in the near term. Quantum science is thus revolutionizing today’s atomic clocks and metrology, providing opportunities to probe fundamental physics and explore emerging quantum phenomena. Recent advances include precise control of atomic interactions to achieve high accuracy, determination of the gravitational time dilation across a few hundred micrometers, and employment of spin entanglement for clock comparison.
