Models josephson junctions to reduce qubit error rates in quantum computing, suggesting improvements in performance.
Josephson junctions are non-linear circuit elements with low dissipation, which makes them suitable building blocks for artificial atoms: macroscopic objects which display quantum behavior. Despite significant progress, the error rates achieved when using these atoms as qubits are still too high for the most useful applications of quantum computing. Accurate theoretical modelling can indicate the way to mitigate some of these errors.
