Ramsey Prize Talk: Quantum science with atom arrays and Rydberg interactions
ORAL · Invited
Abstract
Single atoms provide an ideal setting for explorations in quantum information science by bringing together long coherence times and fast control. What started a couple decades ago as a physics experiment to entangle one pair of atoms has turned into a worldwide race towards large scale quantum computers with thousands of entangled qubits.
This talk will highlight the variety of approaches that are being developed for controlling large qubit arrays. Different atomic elements, encoding choices, trapping geometries, and entanglement protocols are all being combined to achieve scalable processors. In particular I will present an approach based on combining different atomic elements in a single platform with interspecies entanglement provided by Rydberg interactions. Using one element for coherent operations, and the other for coupling to a classical controller provides a viable path towards error corrected quantum processors.
