Scalable Error Correction in Distributed Ion Trap Computers
Daniel K. L. Oi, Simon J. Devitt, Lloyd C. L. Hollenberg
abstract: A major challenge for quantum computation in ion trap systems is scalable
integration of error correction and fault tolerance. We analyze a distributed
architecture with rapid high fidelity local control within nodes and entangled
links between nodes alleviating long-distance transport. We demonstrate
fault-tolerant operator measurements which are used for error correction and
non-local gates. This scheme is readily applied to linear ion traps which
cannot be scaled up beyond a few ions per individual trap but which have access
to a probabilistic entanglement mechanism. A proof-of-concept system is
presented which is within the reach of current experiment.
