Personal notes/

current issues:
  • Last day in rome 21 December 2013 :'(
  • I will start a new research position at Dwave on January 6th 2014

    • View Larger Map (left): Via Carlo Cattaneo View Larger Map (right): University Main Entrance and Edificio Marconi (Fisica), second building on left.

    Current work and research interests:


    		 - Practical quantum computation with O(100) qubits (a recent interest..)
    - Graphical models and message passing algorithms.
    - Typically hard optimization problems. - Statistical Physics
    - Compressive sensing, multi-user detection and channel coding.
    - Boolean logic circuits and networks.

     

    Bayesian Inference course:

    Bayesian Inference, with Aurelien Decelle and Daniele De Martino

    This course will unfortunately not be continued in 2013/2014: thanks to the participants!

     

    Presentations/ other material

    This summer I presented work mostly on constrained variational approximations, the last presentation was Nov 8th which also covered a broader range of my research as part of a job application.
