Robustness of longitudinal transmon readout to ionization
Alex A. Chapple, Alexander McDonald, Manuel H. Muñoz-Arias +1
Multi-photon processes deteriorate the quantum non-demolition (QND) character of the dispersive readout in circuit QED, causing readout to lag behind single and two-qubit gates, in…
High-fidelity gates in a transmon using bath engineering for passive leakage reset
Ted Thorbeck, Alexander McDonald, O. Lanes +6
Leakage, the occupation of any state not used in the computation, is one of the of the most devastating errors in quantum error correction. Transmons, the most common superconducti…
Measurement-Induced Transmon Ionization
Marie Frédérique Dumas, Benjamin Groleau-Paré, Alexander McDonald +4
Despite the high measurement fidelity that can now be reached, the dispersive qubit readout of circuit quantum electrodynamics is plagued by a loss of its quantum nondemolition cha…
