TITLE: Fault-tolerant Operation of a Bacon-Shor Encoded Qubit
SESSION CHAIR: Dr. Ben Brown, University of Sydney, Australia
ABSTRACT:
Many useful quantum algorithms require gate error rates on the order of one failure in one trillion. Fault-tolerant circuit design promises to realize such near-perfect operations with lower fidelity components at the cost of significant operational overhead. However, some devices have reached the sizes and accuracies necessary to test these benefits. In this talk, we will discuss fault-tolerant operation of a Bacon-Shor encoded qubit within a 15 ion chain. We will begin with a review of fault-tolerance, and then focus on the interplay between the choice of code and the device. To conclude, we will touch on some of the challenges beyond near-term demonstrations of error-correction, including detrimental noise sources and the significant classical co-processing required to decode errors at scale. The experiment is a collaboration between the University of Maryland and Duke University
