  Raul Garcia-Patron
Faculty, Max-Planck Institute of Quantum Optics

Raul Garcia-Patron, a native of Madrid, began to study engineering at the University of Brussels (ULB) in the fall of 1998. In July 2003, he graduated from there as Engineer in Physics. From September 2003 to October 2007, Garcia-Patron worked as a Ph.D. student at the Center for Quantum Information and Communication of the University of Brussels (ULB). From November 2007 till December 2010, he worked at the Center for Extreme Quantum Information Theory at MIT. In December 2010 he was awarded an Alexander van Humboldt postdoctoral fellowship. He will join the Theory group of the Max-Planck Institute of Quantum Optics in Garching (Germany) beginning of May 2011.

Majorization Relations in a Two-Mode Squeezer: A Possible Way Towards Solving the Minimum Output Entropy Conjecture for Bosonic Gassian Channels

May 3, 2011 - 2:45 PM - 3:10 PM
RLE Conference Center 36-428

We show that one of the oldest open problems in quantum information theory, the classical capacity of bosonic Gaussian channels, can be reduced to a question about the entanglement at the output of a two-mode squeezer. Using majorization theory we obtain some partial analytical results and numerical evidence for the conjecture.
