Seminars

On an irregular basis various Special Seminars take place at the MPQ. The seminars are organized by scientists of our divisions, administration or staff representatives. The location will be announced with the event.

Special Seminar: Flying qubits: snowballs in Hell (Prof. Dr. Klaus Mølmer)

  • Monday, 05.12. at 3.30 p.m., Room B 0.32
  • Date: Dec 5, 2022
  • Time: 03:30 PM (Local Time Germany)
  • Speaker: Prof. Dr. Klaus Mølmer
  • Niels Bohr Institute, University of Copenhagen
  • Location: Max Planck Institute of Quantum Optics
  • Room: New Lecture Hall, Room B 0.32
Scalable designs for quantum information processing make use of flying qubits, i.e., photon or phonon wave packets that can communicate quantum states and gate operations between remote material (stationary) qubits in a larger network. While a precise description of how a travelling pulse of quantum radiation interacts with a local material quantum system is a crucial theory component in quantum optics and quantum information technologies, our textbooks do not provide a formal description of this elementary interaction process.

Integrated nonlinear optics and Inverse-designed multimode photonics

  • Date: Sep 30, 2022
  • Time: 10:00 AM (Local Time Germany)
  • Speaker: Kiyoul Yang
  • Nanoscale and Quantum Photonics Lab, Stanford University, Stanford, CA, USA
  • Location: Max Planck Institute of Quantum Optics
  • Room: Herbert Walther Lecture Hall
  • Host: MPQ, Laser Spectroscopy Division
In this talk, we will discuss new opportunities involving chip-scale nonlinear optics along with inverse-designed photonic circuits for multi-dimensional information processing. As a specific example, I will introduce recent experiments where we demonstrate natively error-free terabit/s data transmission using integrated frequency combs and multimode silicon photonics.

Special Seminar: Absolute Measurement of a THz Transition Frequency Referenced to a Magnetic Dipolar Transition in Ca+ ion

Special Seminar: Absolute Measurement of a THz Transition Frequency Referenced to a Magnetic Dipolar Transition in Ca+ ion
  • Date: Sep 6, 2022
  • Time: 11:00 AM (Local Time Germany)
  • Speaker: Dr. Caroline Champenois
  • Aix-Marseille University, CNRS, Institute de Physique des Interactions Ioniques et Moléculaires, Marseille, France
  • Location: Max Planck Institute of Quantum Optics
  • Room: Hörsaal, Raum B 0.32 / New lecture hall, Room B 0.32
  • Host: MPQ, Laser Spectroscopy Division
A three-photon Coherent Population Trapping is observed by the dark line it induces on the laser induced fluorescence of a laser-cooled Ca+ ion cloud. This dark line is referenced to a magnetic dipolar transition at 1.8 THz, between two fine-structure sub-state of a metastable state. We explore the performance of such a system for frequency metrology in the THz domain. [more]
