    "abstract": "Quantum error correcting codes have been shown to have the ability of making\nquantum information resilient against noise. Here we show that we can use\nquantum error correcting codes as diagnostics to characterise noise. The\nexperiment is based on a three-bit quantum error correcting code carried out on\na three-qubit nuclear magnetic resonance (NMR) quantum information processor.\nUtilizing both engineered and natural noise, the degree of correlations present\nin the noise affecting a two-qubit subsystem was determined. We measured a\ncorrelation factor of c=0.5+/-0.2 using the error correction protocol, and\nc=0.3+/-0.2 using a standard NMR technique based on coherence pathway\nselection. Although the error correction method demands precise control, the\nresults demonstrate that the required precision is achievable in the\nliquid-state NMR setting.",
