Seminars


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.

Certification of Quantum Measurements and New Entangled Quantum Probes

Certification of Quantum Measurements and New Entangled Quantum Probes
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]

Part 1: Scattering theory in quantum opticsPart 2: Scaling up and understanding the limits of photonic inverse design

Part 1: Scattering theory in quantum optics Part 2: Scaling up and understanding the limits of photonic inverse design
Part 1: Quantum optical systems can often be modelled as a low-dimensional quantum system (such atwo-level system, Jaynes-Cummings system etc.) coupling to an electromagnetic bath. [more]

Fundamental science by high-power microwaves - Millimeter-wave spectroscopy of positronium hyperfine structure and further ( Prof. Dr. Akira Miyazaki)

Fundamental science by high-power microwaves - Millimeter-wave spectroscopy of positronium hyperfine structure and further
The microwave technology has been one of the important tools in fundamental physics since Rabi's pioneering work on hydrogen atoms. In this seminar, direct spectroscopy of positronium hyperfine structure with very high frequency microwaves, often referred to as millimeter or sub-THz waves, will be discussed. [more]

Direct laser cooling to Bose-Einstein condensation (Alban Urvory)

Direct laser cooling to Bose-Einstein condensation
Laser cooling methods are virtually ubiquitous for the production of ultracold quantum gases. Yet in order to reach quantum degeneracy, a complementary step of lossy and inefficient evaporative cooling has so far been required (with few specific exceptions). [more]
