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.Month:
SDP relaxations for the certification of properties of many-body quantum states
SDP relaxations for the certification of properties of many-body quantum states (Flavio Baccari)
- Date: Dec 6, 2018
- Time: 11:30
- Speaker: Flavio Baccari
- ICFO – The Institute of Photonic Sciences
- Location: Max-Planck-Institut für Quantenoptik
- Room: B 2.46
- Host: MPQ, Theory Division
Understanding the properties of many-body systems is one of the crucial questions for the development of quantum technologies. An ubiquitous problem is to certify that a given many-body quantum system satisfies an operational property: is this given system in an entangled state? Does it contain the solution to a classical optimisation problem? [more]
The 2nd Law: History and Fiction
The 2nd Law: History and Fiction (Prof. Assa Auerbach)
- Date: Dec 5, 2018
- Time: 16:30
- Speaker: Prof. Assa Auerbach, Technion, Haifa, Israel
- Technion - Israel Institute of Technology
- Location: Max-Planck-Institut für Quantenoptik
- Room: Hörsaal, Raum B 0.32 / New lecture hall, Room B 0.32
- Host: MPQ, IMPRS-QST
The talk The 2nd Law: History and Fiction discusses the history of Maxwell’s Demon, the Second Law of Thermodynamics, and its connection to Information Theory. It shows how these concepts can be explained to non-physicists in a comic book of an adventure story called “Max the Demon vs Entropy of Doom’’. [more]
Entanglement in non-unitary critical spin chains
Entanglement in non-unitary critical spin chains (Romain Couvreur)
- Date: Dec 5, 2018
- Time: 10:30
- Speaker: Romain Couvreur
- ENS Paris
- Location: Max-Planck-Institut für Quantenoptik
- Room: B 2.46
- Host: MPQ, Theory Division
Entanglement entropy has proven invaluable to our understanding of quantum criticality. It is natural to try to extend the concept to “nonunitary quantum mechanics”, which has seen growing interest from areas as diverse as open quantum systems, noninteracting electronic disordered systems, or nonunitary conformal field theory (CFT).

Realizing Feynman’s Dream of a Quantum Simulator
IMPRS-APS: Realizing Feynman’s Dream of a Quantum Simulator (Prof. Immanuel Bloch)
- Date: Dec 4, 2018
- Time: 11:30
- Speaker: Prof. Immanuel Bloch
- Ludwig Maximilian University of Munich and Max Planck Institute of Quantum Optics)
- Location: Max-Planck-Institut für Quantenoptik
- Room: New Lecture Hall, Room B 0.32
- Host: IMPRS-APS
More than 30 years ago, Richard Feynman outlined his vision of a quantum simulator for carrying out complex calculations on physical problems. Today, his dream is a reality in laboratories around the world. [more]
Quantum physics with compound atom-ion systems
Quantum physics with compound atom-ion systems (Dr. Antonio Negretti)
- Date: Nov 28, 2018
- Time: 10:30
- Speaker: Dr. Antonio Negretti
- Associate Professor at Center for Optical Quantum Technologies, Universität Hamburg
- Location: Max-Planck-Institut für Quantenoptik
- Room: Hörsaal, Raum B 0.32 / New lecture hall, Room B 0.32
- Host: MPQ, Theory Division, hosted by Dr. Richard Schmidt
- Contact: richard.schmidt@mpq.mpg.de
In this talk I shall illustrate how ultracold quantum systems of atoms and ions can be used for quantum simulation and information processing as well as for investigating many-body quantum physics. I shall thus present a few theoretical examples on how to control an atomic bosonic Josephson junction with a single trapped ion, the formation of molecular ions, and how to engineer long-ranged atom-ion interactions with laser fields and Rydberg excitations.
