Recovery Algorithm for Correlated Errors in Permutation-Invariant Quantum Codes
Omprakash Chandra, Yingkai Ouyang, Gopikrishnan Muraleedharan +1
Quantum Error Recovery (QER) uses knowledge of the error channel acting on a quantum system to find optimal recovery maps. The scheme restores the uncorrupted state with a fidelity…
A theory of quantum error correction for permutation-invariant codes
Yingkai Ouyang, Gavin K. Brennen
We present for the first time a general theory of error correction for permutation invariant (PI) codes. Using representation theory of the symmetric group we construct efficient a…
The equivalence of quantum deletion and insertion errors on permutation-invariant codes
Lewis Bulled, Yingkai Ouyang
Quantum synchronisation errors are a class of errors that change the number of qubits in a quantum system. The classical error correction of synchronisation errors has been well-st…
