Analog Quantum Simulation: from physics to chemistry (Ignacio Cirac)

Analog Quantum Simulation: from physics to chemistry

Date: Apr 16, 2020
Time: 05:00 PM (Local Time Germany)
Speaker: Prof. Dr. J. Ignacio Cirac
Director at MPQ Theory Division

Many-body systems are very hard to simulate due to the explosion of parameters with the system size. Quantum computers can help in this task, although one may need scalable systems, something that is out of reach in the short run. An attractive alternative is provided by analog quantum simulators which, even though they are not universal, they can still be tuned to study interesting problems. Atoms in optical lattices seem to be ideally suited for that task. Most of the proposals of such simulators have focused so far on condensed matter or high energy physics problems. In this talk I will show how one can extend the range of problems to other scenarios, especially to quantum chemistry. [more]

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]

Probing many-body quantum states with randomized measurements

Date: Feb 12, 2020
Time: 11:30 AM (Local Time Germany)
Speaker: Andreas Elben
IQOQI Institute of Quantum Optics and Quantum Information, Innsbruck, Austria
Location: Herbert Walther Lecture Hall, MPI für Quantenoptik, Garching
Host: Ignacio Cirac

Randomized measurements are a technique to probe many-body quantum states beyond familiar, low-order observables. In this talk, I introduce the technique using the example of measuring the second-order Rényi entropy in a trapped ion quantum simulator. [more]
