A Mixed-Species Atom Array for Quantum Computing and Simulation

In this 37-minute conference talk from the Erwin Schrödinger International Institute for Mathematics and Physics (ESI), Dr. Giulia Semeghini presents cutting-edge research on mixed-species atom arrays for quantum computing applications. Delivered as part of the Thematic Programme on "Entanglement in Many-body Quantum Matter: Dynamics, Dissipation, Equilibration," the presentation explores recent advancements in Rydberg atom arrays and introduces innovative opportunities created by dual-species arrays combining alkali and alkaline-earth atoms. Learn about how trapped arrays of interacting Rydberg atoms have become a leading platform for quantum information processing due to their large system size and programmability. Discover the advantages of adding a second atomic species, including selective qubit control, asymmetric Rydberg interactions, and novel quantum computing architectures. The talk details ongoing efforts to create a continuously reloaded, programmable atom array based on a mixture of Rb and Yb atoms, and examines applications ranging from combining coherent and dissipative dynamics for quantum information processing to simulating lattice gauge theories.
