Quantum Science with Arrays of Rydberg Atoms and Molecules

Join us for the 837th Wilhelm and Else Heraeus Seminar "Quantum Science with Interacting Arrays of Rydberg Atoms and Molecules" at the Physikzentrum Bad Honnef, Germany, from July 27th – August 1st, 2025.

• This workshop aims to bring together world-leading experts and young aspiring researchers in the field of quantum science of optical tweezer arrays of interacting Rydberg atoms and molecules. It shall promote scientific exchange and foster a strong community spirit in the field.
• The program will feature distinguished invited speakers on quantum optics, quantum metrology, quantum simulation, and quantum computing with atomic and molecular systems in optical tweezer arrays.
• For all participants, complimentary full-board accommodation is provided on-site by the Wilhelm and Else Heraeus Foundation. No conference fee applies. Please note that the total number of participants is limited to 80.

Atomic and molecular systems in optical tweezer arrays foster various applications reaching from quantum optics and quantum metrology through quantum simulation all the way to quantum computing. The great success of this platform is rooted in the near-perfect isolation of the atomic particles from the environment and in the advanced experimental capabilities and theoretical methods, enabling excellent control and detection at the single-particle level. The strong interactions of Rydberg atoms and of polar molecules take a central role in the fundamental aspects and for the emerging applications. In quantum simulations, recent breakthroughs in the control of individual atoms have allowed for simulating quantum spin models of several hundred spins, beyond the realm that can be simulated exactly on classical machines. A new frontier has recently emerged from these experiments in the quest to realize digital quantum computers, including the ability to implement efficient protocols for quantum error correction. New developments in the field of quantum metrology, such as the application of entangled states, are opening novel venues for precision measurements. Given by the high dynamics in this field, new directions are constantly emerging, such as architectures combining different atomic species or hybrid systems of atoms and molecules. This ongoing evolution will pave the way for the investigation of ever more complex quantum model systems in the future.

The workshop is organized by the Technical University of Darmstadt, the Max Planck Institute of Quantum Optics, the University of Stuttgart, and the Wilhelm and Else Heraeus Foundation.
