Experimental demonstration of quantum fault tolerance posted to the arXiv


 
The Trapped Ion Quantum Information group at the JQI and the University of Maryland have demonstrated fault-tolerant quantum error correction experimentally.  A linear chain of 5 ytterbium ions was used to encode a logical qubit using the [[4,2,2]] code and measure the stabilizers.  The Brown Lab provided theoretical support.  Congratulations to the UMD-Gatech collaboration!
