Learning logical Pauli noise in quantum error correction
Thomas Wagner, Hermann Kampermann, Dagmar Bruß +1
The characterization of quantum devices is crucial for their practical implementation but can be costly in experimental effort and classical postprocessing. Therefore, it is desira…
Quantum Grid States and Hybrid Graphs
Biswash Ghimire, Thomas Wagner, Hermann Kampermann +1
Using the signed laplacian matrix, and weighted and hybrid graphs, we present additional ways to interpret graphs as grid states. Hybrid graphs offer the most general interpretatio…
Pauli channels can be estimated from syndrome measurements in quantum error correction
Thomas Wagner, Hermann Kampermann, Dagmar Bruß +1
The performance of quantum error correction can be significantly improved if detailed information about the noise is available, allowing to optimize both codes and decoders. It has…
Optimal noise estimation from syndrome statistics of quantum codes
Thomas Wagner, Hermann Kampermann, Dagmar Bruß +1
Quantum error correction allows to actively correct errors occurring in a quantum computation when the noise is weak enough. To make this error correction competitive information a…
Symmetries for a High Level Neural Decoder on the Toric Code
Thomas Wagner, Hermann Kampermann, Dagmar Bruß
Surface codes are a promising method of quantum error correction and the basis of many proposed quantum computation implementations. However, their efficient decoding is still not…
Analysis of quantum error correction with symmetric hypergraph states
Thomas Wagner, Hermann Kampermann, Dagmar Bruß
Graph states have been used to construct quantum error correction codes for independent errors. Hypergraph states generalize graph states, and symmetric hypergraph states have been…
