Quantum MERA Channels

November 19, 2008 - 8:55-9:20am

RLE Conference Center - 36-428


Tensor networks representations  of  many-body quantum systems can be described in terms of quantum channels.  We focus on channels associated with the Multi-scale Entanglement Renormalization Ansatz (MERA) tensor network that has been recently introduced to efficiently describe critical systems. Our approach allows to compute the MERA correspondent to the thermodynamical limit of a critical system introducing a transfer matrix formalism and to relate the system critical exponents to the convergence rates of the associated channels.


Research field: Quantum Information and Quantum Optics 

Dr. Giovannetti have published more than 80 publications in international journals including Nature, Science, Phys. Rev. Lett. and I attended more than 15 international conferences giving invited and contributed talks. Education and Positions: 2008 I have been recently awarded with a 1.600.000 Euros grant by the Italian Government on  a research project on Quantum Interferometric Effects in Quantum Hall systems (ERC-FIRB grant 2008).
