Saving superconducting quantum processors from decay and correlated errors generated by gamma and cosmic rays
Abstract Error-corrected quantum computers can only work if errors are small and uncorrelated. Here, I show how cosmic rays or stray background radiation affects superconducting qubits by modeling the phonon to electron/quasiparticle down-conversion physics. For present designs, the model predicts a...
