Physics Colloquium

Optical atomic clocks in the age of quantum information processing

Optical atomic clocks provide our most precise and accurate measurements of time and frequency, with impact ranging from tests of fundamental physics to relativistic geodesy. A new frontier for these clocks has emerged in the form of neutral-atom arrays, which combine microscopic single-particle control, highly coherent qubits, and programmable interactions. This convergence lets us apply techniques from quantum information processing to precision measurement, which allows us not only to further improve optical-clock performance but also to explore new directions, such as the interplay of quantum mechanics and relativity. In this talk, I will give an overview of what this convergence enables, discuss experiments that have begun to explore entanglement-enhanced optical clocks, and outline the research program we are building at Caltech.
