Quantum Error Correction in Spatially Correlated Quantum Noise
arXiv:quant-ph/0505153 · doi:10.1103/PhysRevLett.95.230503
Abstract
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 kind of noise correlations have a strong negative impact on quantum error correction.
