Quantum error correction of decoherence and faulty control operations forms the backbone of all of quantum information processing. Despite remarkable progress on this front since the discovery of quantum error correcting codes more than a decade ago, important open problems in both theory and applications to real physical systems remain.
The Fourth International Conference on Quantum Error Correction, hosted by Georgia Tech and UMD/NIST, will bring together a wide group of experts to discuss all aspects of decoherence control and fault tolerance. Though the subject is still mostly theoretical in nature, the conference will include talks surveying the latest experimental progress, and will seek to promote an interaction between theoreticians and experimentalists.
Topics of interest include, in random order: fault tolerance and thresholds, pulse control methods (dynamical decoupling), hybrid methods, applications to cryptography, decoherence-free subspaces and noiseless subsystems, operator quantum error correction, advanced codes (convolutional codes, catalytic, entanglement assisted, ...), topological codes, fault tolerance in the cluster model, fault tolerance in linear optics QC, fault tolerance in condensed matter systems, unification of error correction paradigms, self-correcting systems, error correction/avoidance via energy gaps, error correction in adiabatic QC, composite pulses, continuous-time QEC, error correction for specific errors (e.g., spontaneous emission), etc.
