"Sensitivity and Stability of Quantum Fluids in Driven Disorder" (Prof. Artur Widera)

• Date: May 6, 2025
• Time: 02:30 PM (Local Time Germany)
• Speaker: Prof. Artur Widera
• RPTU Kaiserslautern-Landau, Physics Department and State Research Center OPTIMAS, Kaiserslautern, Germany
• Location: Max Planck Institute of Quantum Optics, Hans-Kopferman-Straße 1, 85748 Garching
• Room: Herbert Walther Lecture Hall
• Host: Max Planck Institute of Quantum Optics

The interplay of local perturbations and interactions is key for understanding quantum many-body systems. We study lithium Fermi gases in time-dependent disorder, using speckle potentials with quenches or finite correlation times. [more]

“Quantum Processors and Quantum Networks – Atom-by-Atom” (Prof. Hannes Bernien)

• Date: May 13, 2025
• Time: 02:30 PM (Local Time Germany)
• Speaker: Prof. Hannes Bernien
• University of Innsbruck & IQOQI, University of Chicago
• Location: Max Planck Institute of Quantum Optics, Hans-Kopferman-Straße 1, 85748 Garching
• Room: Herbert Walther Lecture Hall
• Host: Max Planck Institute of Quantum Optics

Reconfigurable arrays of neutral atoms have emerged as a leading platform for quantum science. Their excellent coherence properties combined with programmable Rydberg interactions have led to intriguing observations such as quantum phase transitions, the discovery of quantum many-body scars, and novel quantum computing architectures.

"Embracing uncertainty: a photonic approach to probabilistic computing" (Prof. Wolfram Pernice)

• Date: Jun 3, 2025
• Time: 02:30 PM (Local Time Germany)
• Speaker: Prof. Wolfram Pernice
• Kirchhoff-Institut für Physik, Universität Heidelberg
• Location: Max Planck Institute of Quantum Optics, Hans-Kopferman-Straße 1, 85748 Garching
• Room: Herbert Walther Lecture Hall
• Host: Max Planck Institute of Quantum Optics

I will discuss advances in photonic computing architectures leveraging hardware noise as a computational resource. Using nanoscale phase-change materials allows in-memory processing of probabilistic data. Photonic crossbar arrays utilizing chaotic light as entropy sources enable parallel, energy-efficient, high-speed probabilistic machine learning beyond traditional hardware limits. [more]
