JILA Thesis Defense - Alec Cao
Event Title: High-fidelity gates and quantum-enhanced metrology in a programmable optical clock
Speaker Name:Alec Cao
Abstract: In this defense I will discuss experimental efforts in bringing the versatile controls of atom arrays, a leading platform for quantum computing, to the world of optical atomic clocks, the most precise measurement devices ever constructed. Using arrays of strontium atoms, we demonstrate the highest fidelity single-qubit gates on an optical transition to date, the first realization of GHZ states on a long-lived neutral-atom optical qubit, and a novel method for reducing Rydberg-induced decoherence with autoionization. We further demonstrate the use of GHZ states and spin-squeezed states to realize entanglement-enhanced optical clock performance.
