Quantum computing and networking w/ alkali atom qubit arrays | Qiskit Seminar Series w/ Mark Saffman

Episode 169
Arrays of atoms with interactions provided by highly excited Rydberg states provide a setting where atomic physics takes on extreme properties which are being harnessed for quantum applications. In the last few years remarkable progress has been achieved with neutral atom arrays, and they are now established as a leading platform for quantum computing.
The talk will present our progress on gate model quantum computing with atom arrays based on a scalable architecture incorporating stationary atoms and rapid scanning of focused control beams. Approaches to realizing fast mid-circuit measurements[1] and quantum error correction will be presented. Long range Rydberg interactions are a viable approach for fast implementation of non-local qLDPC codes[2]. For longer distance quantum interfaces integration of atom arrays with photon collection optics provides a path towards distributed quantum processing[3].

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 was the first to demonstrate a quantum CNOT gate for the deterministic entanglement of a pair of neutral atoms. This was done using dipole mediated 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 has been recognized with an Alfred P. Sloan fellowship, a Vilas Associate Award, the WARF Innovation Award, and is a fellow of the American Physical Society, and Optica. He has been active in professional service including two decades as an Associate Editor at the Physical Review, and is the director of The Wisconsin Quantum Institute. He also serves as Chief Scientist for Quantum Information at Infleqtion, Inc. .

quite informative talk!

atom array is not equal to superposition qubit right?
