Measurement-induced state transitions across the fluxonium qubit landscape
Alex A. Chapple, Boris M. Varbanov, Alexander McDonald +1
Understanding the mechanisms that limit high-fidelity readout in circuit quantum electrodynamics is essential for its optimization. Multi-photon resonances are understood to be a l…
Fast, high-fidelity Transmon readout with intrinsic Purcell protection via nonperturbative cross-Kerr coupling
Guillaume Beaulieu, Jun-Zhe Chen, Marco Scigliuzzo +5
Dispersive readout of superconducting qubits relies on a transverse capacitive coupling that hybridizes the qubit with the readout resonator, subjecting the qubit to Purcell decay…
Balanced cross-Kerr coupling for superconducting qubit readout
Alex A. Chapple, Othmane Benhayoune-Khadraoui, Simon Richer +1
Dispersive readout, the standard method for measuring superconducting qubits, is limited by multiphoton qubit-resonator processes arising even at moderate drive powers. These proce…
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…
