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.

The Optical Society (OSA)

Date: Feb 26, 2020
Time: 01:30 PM (Local Time Germany)
Speaker: Dr. Claus Roll
Director, OSA Europe
Location: Max Planck Institute of Quantum Optics
Room: Herbert Walther Lecture Hall
Host: MPQ, Laser Spectroscopy Division

OSA presents its actions and programs for the “optics and photonics” community: students, faculty and industry from all over the world. Benefits will be shown for those relating with OSA at various levels, including the journal publishing program, including reviewer policies and rewarding. On demand, a more in depth description of student chapters will be given, its setup, the benefits (not only to students) and how to maintain and develop it. Everybody is welcome (OSA members and non-members). [more]

Quantifying the incompatibility of quantum measurements

Date: Dec 17, 2019
Time: 11:30 AM (Local Time Germany)
Speaker: Georgios Styliars, University of Southern California, Los Angeles, USA
Location: Max-Planck-Institut für Quantenoptik
Room: Herbert Walther Lecture Hall

Incompatibility in quantum mechanics is famously captured through uncertainty relations. In this talk, we adopt the perspective that incompatibility can be fundamentally understood in terms of emulation of measurements by other measurements. [more]

Ultrafast mid-infrared laser systems and broad-band precision molecular spectroscopy

Date: Nov 13, 2019
Time: 02:00 PM (Local Time Germany)
Speaker: Prof. Dr. Gianluca Galzerano
Istituto di Fotonica e Nanotecnologie - Consiglio Nazionale delle Ricerche, and Dipartimento di Fisica - Politecnico di Milano
Location: Max-Planck-Institut für Quantenoptik
Room: Herbert Walther Lecture Hall

Femtosecond laser sources operating in the near- and middle-infrared (mid-IR) spectral range with high- repetition rates are of upmost interest for a variety of applications ranging from ultrafast spectroscopy, high-resolution and broadband spectroscopy, quantum optics, frequency metrology and synthesis of mid-IR optical frequency combs.

Certification of Quantum Measurements and New Entangled Quantum Probes

Date: Jul 31, 2019
Time: 11:30 AM (Local Time Germany)
Speaker: Prof. Gerardo Ortiz
Departement of Physics, Indiana University, Bloomington, USA
Location: Max Planck Institute of Quantum Optics
Room: Herbert Walther Lecture Hall

In the quantum information literature, self-testing refers to the action of uniquely determining a quantum state based solely on the statistics of measurement outcomes and minimal assumptions. These quantum self-testing protocols are more stringent than well-known Bell tests. While violation of a Bell inequality for a bipartite system establishes that its quantum state is entangled, it cannot certify, for instance, that its quantum state is maximally entangled. We extend self-testing techniques to certification of quantum measurements in various physical settings. [more]
