Quantum Computation and Quantum Spin Systems

August 10-14 2009


Long-term programme:

Entanglement and correlations
in many-body quantum mechanics

     August 18 – October 17 2009

Organizers: Bruno Nachtergaele (UC Davis)

During the last decade, we have seen spectacular advances in the field of strongly correlated quantum many-body systems: the observation of quantum phase transitions in optical lattices and the realization that many-body entanglement can be exploited to build quantum computers are only two of the notable breakthroughs. The description of strongly correlated quantum systems and the associated entanglement structure and complexity is still largely unexplored territory, and represents one of the big challenges and opportunities in theoretical physics and associated fields. This is also the main theme of the workshop and long-term programme.

The workshop and programme aim at bringing experts from a wide variety of fields together to work and discuss on the topics of strongly correlated many-body quantum systems, entanglement theory, quantum computing, complexity theory. Particular topics of interest include the simulation of quantum many-body systems, topological quantum order, real-space renormalization group methods, quantum complexity theory, quantum spin glasses, area laws and entanglement entropy, quantum many-body dissipative processes, quantum computation, quantum phase transitions, entanglement in quantum field theories,  ...

The venue is the Erwin Schrodinger Institute for Mathematical Physics in the center of Vienna. This Institute is particularly well suited for accommodating  such a program, as it provides desks and a stimulating environment with plenty of blackboards and places to discuss.  All participants will also receive a daily allowance that is sufficient to cover hotel costs and local expenses.


About the workshop (August 10-14 2009)

The workshop will be on topics that lie at the interface between quantum many-body physics and quantum computation. An event of a similar nature was held in Leiden in 2007.
During the workshop we expect to discuss topics such as classical and/or quantum simulations of quantum many-body systems, entanglement scaling laws, characterization of quantum Hamiltonians for the purpose of topological quantum computation, adiabatic quantum computation, quantum complexity theory.

The format of the workshop is to have approximately three talks per day, leaving ample time for discussion between the participants. There will be a possibility to present posters at the workshop. Confirmed speakers for the workshop include

About the programme (August 18 – October 17 2009)

The programme will be focused on the topic of entanglement and correlations in many-body systems. This covers a wide range of current research in the fields of mathematical physics, theoretical condensed matter physics, quantum computation, computational complexity and statistical physics. Particular attention will be paid to the recent developments in the field of real-space renormalization group methods for quantum many-body systems.


More information on both the workshop and programme will be posted later.
