Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Far from Perfect: Quantum Error Correction with (Hyperinvariant) Evenbly Codes
Matthew Steinberg, Junyu Fan, Robert J. Harris +3
We introduce a new class of qubit codes that we call Evenbly codes, building on a previous proposal of hyperinvariant tensor networks. Its tensor network description consists of lo…
Parallel decoding of multiple logical qubits in tensor-network codes
Terry Farrelly, Robert J. Harris, Nathan A. McMahon +1
We consider tensor-network stabilizer codes and show that their tensor-network decoder has the property that independent logical qubits can be decoded in parallel. As long as the e…
Tensor-network codes
Terry Farrelly, Robert J. Harris, Nathan A. McMahon +1
Inspired by holographic codes and tensor-network decoders, we introduce tensor-network stabilizer codes which come with a natural tensor-network decoder. These codes can correspond…
Decoding Holographic Codes with an Integer Optimisation Decoder
Robert J. Harris, Elliot Coupe, Nathan A. McMahon +2
We develop a most likely error Pauli error decoding algorithm for stabiliser codes based on general purpose integer optimisation. Using this decoder we analyse the performance of h…
Calderbank-Steane-Shor Holographic Quantum Error Correcting Codes
Robert J. Harris, Nathan A. McMahon, Gavin K. Brennen +1
We expand the class of holographic quantum error correcting codes by developing the notion of block perfect tensors, a wider class that includes previously defined perfect tensors.…
