QUANTUM ERROR CORRECTION USING NEURAL NETWORKS
This abstract first appeared for US patent application 18237204 titled 'QUANTUM ERROR CORRECTION USING NEURAL NETWORKS
Original Abstract Submitted
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for detecting errors in a computation performed by a quantum computer. In one aspect, a method comprises obtaining error correction data for each of a plurality of time steps during the computation; initializing a decoder state; and for each of the plurality of time steps: generating an intermediate representation; and processing a time step input through a Transformer neural network to update the decoder state for the time step. The method comprises generating a prediction of whether an error occurred in the computation from the decoder state for the last time step of the plurality of time steps.
