Data-driven decoding of quantum error correcting codes using graph neural networks

Moritz Lange, Pontus Havström, Basudha Srivastava +6

To leverage the full potential of quantum error-correcting stabilizer codes it is crucial to have an efficient and accurate decoder. Accurate, maximum likelihood, decoders are comp…

Colossal transverse magnetoresistance due to nematic superconducting phase fluctuations in a copper oxide

Jonatan Wårdh, Mats Granath, Jie Wu +3

Electronic anisotropy (or `nematicity') has been detected in all main families of cuprate superconductors by a range of experimental techniques -- electronic Raman scattering, THz…

Nematic single-component superconductivity and loop-current order from pair-density wave instability

Jonatan Wårdh, Mats Granath

We investigate the nematic and loop-current type orders that may arise as vestigial precursor phases in a model with an underlying pair-density wave (PDW) instability. We discuss h…

The XYZ hexagonal stabilizer code

Basudha Srivastava, Anton Frisk Kockum, Mats Granath

We consider a topological stabilizer code on a honeycomb grid, the "XYZ" code. The code is inspired by the Kitaev honeycomb model and is a simple realization of a "matching cod…

Error-rate-agnostic decoding of topological stabilizer codes

Karl Hammar, Alexei Orekhov, Patrik Wallin Hybelius +4

Efficient high-performance decoding of topological stabilizer codes has the potential to crucially improve the balance between logical failure rates and the number and individual e…

Applying quantum approximate optimization to the heterogeneous vehicle routing problem

David Fitzek, Toheed Ghandriz, Leo Laine +2

Quantum computing offers new heuristics for combinatorial problems. With small- and intermediate-scale quantum devices becoming available, it is possible to implement and test thes…
