DESCRIPTION:Speaker: Christopher Eichler\nhosted by Johannes Fink\nAbstract
 : The ability to perform logical quantum operations fault-tolerantly by co
 rrecting unavoidable errors induced by control inaccuracies and decoherenc
 e\, will be essential for building and operating large-scale quantum compu
 ters. In my talk\, I present our recent demonstration of repeated quantum 
 error correction using a surface code\, which  is known for it exceptional
 ly high error threshold and its compatibility with planar qubit architectu
 res featuring nearest-neighbor coupling.  The code implemented in our expe
 riments uses 17 physical qubits\, nine of  of which encode the logical inf
 ormation and eight of which perform repeated measurements of error syndrom
 es. By decoding the syndrome data in post-processing we preserve initializ
 ed logical states with a low error probability of 3% per cycle. The demons
 tration of repeated\, fast and high-performance quantum error correction s
 upports our understanding that fault-tolerant quantum computation will eve
 ntually be realizable.
