TITRE / TITLE : Scalable control of quantum systems

RESUME / ABSTRACT : Quantum information processing promise to develop computing, communication or sensing devices that are more powerful than their classical counterparts. It does so by encoding and manipulating information in states that are either difficult or impossible to reach classically. Unfortunately these states are typically extremely fragile. To turn the ideas of quantum information processing into reality, we need to make quantum information robust to imperfection and imprecision inherent to realistic devices. In the mid 1990's, a theory of quantum error correction was discovered and accuracy threshold theorems were proved showing that error can be controlled using a reasonable amount of resources as long as the error rate is smaller than a certain threshold. I will describe how quantum error correction works and talk about recent progress in this field both in theoretically and experimentally.
