Quantum Cafe: Ignacio Cirac

Date & Time

Title: Quantum Algorithms for Quantum Simulation and Small Devices

Abstract: I will present some simple quantum algorithms to prepare the ground state and the corresponding energy of many-body Hamiltonians. One of them is based on a power method, similar to the one used in classical problems. The second one is heuristic and aims at optimizing computational resources in small quantum computers. I will also present a hybrid quantum-classical algorithm to solve 3SAT problems with small quantum computers that significantly speeds up its fully classical counterpart.

Quantum Café is CCQ’s ongoing seminar series: open to all bona fide members of the greater NYC scientific community and held every second week, Quantum Café presents a series of informal, highly interactive talks, typically by external speakers, which present the most interesting recent developments and open questions in our field.

About the Speaker

Ignacio Cirac has been Director of the Theory Division at the Max-Planck Institute for Quantum Optics since December 2001. He was originally trained in Theoretical Physics at the University Complutense of Madrid (B.S. 1988) and obtained his PhD in Theoretical Quantum Optics in 1991 from the same university. He was Professor Titular at the University of Castilla-La Mancha (Spain) from 1991 to 1996, and carried out a postdoc at the same time at the Joint Institute for Laboratory Astrophysics (University of Colorado). He then moved to the University of Innsbruck (Austria) as a Professor of Theoretical Physics. He has also been honorary professor at the Technical University of Munich (Germany) since 2002. His main areas of research are the theoretical description of atomic systems interacting with light, and the development of a theory of Quantum Information.
