Quantum Computing with neutral atoms at planqc

Dr. Sebastian Blatt
planqc, Garching, Germany
Sebastian Blatt is the co-founder and Chief Technology Officer of planqc. Prior to that, he led research groups at Ludwig Maximilian University of Munich and the Max Planck Institute of Quantum Optics. He is currently focused on the development of scalable quantum computers within planqc and the Munich Quantum Valley initiative.

Analog quantum simulators based on ultracold atoms trapped in optical lattices can be used to study condensed-matter systems with single-site resolution. The quest for more control over individual atoms in such systems has culminated in a new generation of experiments based on atom arrays assembled using optical tweezers. These atom arrays can be created rapidly in arbitrary two- and three-dimensional geometries, and atoms in these arrays can be entangled using long-range Rydberg interactions. Based on these developments, atom arrays have emerged as one of the most promising platforms for building digital quantum computers because (1) atoms can realize qubits with coherence times of many seconds, (2) they exhibit no manufacturing variations, and (3) it is straightforward to scale up to arrays with thousands of qubits. I will present the digital quantum computer demonstrators developed in the academic projects within Munich Quantum Valley, as well as the commercial quantum computers developed at planqc.
