Abstract

Progress in quantum computing with neutral atom qubits has advanced rapidly with the development of large 2D arrays and high fidelity entangling gates and qubit measurements. As with all qubit platforms the challenge of establishing rapid connectivity between large numbers of qubits must be overcome for scalable computation. Neutral atoms can be entangled at short length scales via Rydberg interactions, at medium length scales with physical transport, and at long scales via photons. I will discuss these options, including our recent progress towards remote, photon mediated entanglement with multiple atomic species. 

Bio

Mark Saffman is an experimental physicist working in the areas of atomic physics, quantum and nonlinear optics, and quantum information processing. His research team has been a pioneer in quantum computing with atomic qubits. They were the first to demonstrate a quantum CNOT gate for the deterministic entanglement of a pair of neutral atoms. This was done using interactions between highly excited Rydberg atoms.He is currently developing scalable arrays of neutral atoms for quantum computation, communication, and sensing applications.

He is the Johannes Rydberg Professor of Physics at the University of Wisconsin-Madison and is a fellow of the American Physical Society and Optica. He has been recognized with an Alfred P. Sloan fellowship, the WARF Innovation Award, the APS Norman F. Ramsey Prize, and the John Stewart Bell Prize. He has been active in professional service including two decades as an Associate Editor at the PhysicalReview, and is the former director of The Wisconsin Quantum Institute. He also serves as Chief Scientist for Quantum Information at Infleqtion.
