Quantum Error Correction in Spatially Correlated Quantum Noise
Rochus Klesse, Sandra Frank · Physical Review Letters · 2005
We consider quantum error correction of quantum noise that is created by a local interaction of qubits with a common bosonic bath. The possible exchange of bath bosons between qubits gives rise to spatial and temporal correlations in the noise. We find that these kinds of noise correlations have a strong negative impact on quantum error correction.
