Résumé : Superconducting quantum circuits show great potential as a practical quantum information technology. However, noise causes decoherence and loss of fidelity in quantum processes, preventing full-scale quantum processors from being built. I will discuss our ongoing experiments to harness noise to improve coherence and fidelity. These include adding engineering the quantum bath to turn bad qubits into a good refrigerators; adding "generalized Markovian" noise to suppress the effects of environmental Markovian noise; and using noise correlations between different qubits to design better quantum error correction algorithms.
