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…
How the Kerr-Cat Qubit Dies -- And How to Rescue It
Othmane Benhayoune-Khadraoui, Cristóbal Lledó, Alexandre Blais
Kerr-cat qubits have been experimentally shown to exhibit a large noise bias, with one decay channel suppressed by several orders of magnitude. In superconducting implementations,…
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…
Toolbox for nonreciprocal dispersive models in circuit QED
Lautaro Labarca, Othmane Benhayoune-Khadraoui, Alexandre Blais +1
We provide a systematic method for constructing effective dispersive Lindblad master equations to describe weakly anharmonic superconducting circuits coupled by a generic dissipati…
Fast Flux-Activated Leakage Reduction for Superconducting Quantum Circuits
Nathan Lacroix, Luca Hofele, Ants Remm +14
Quantum computers will require quantum error correction to reach the low error rates necessary for solving problems that surpass the capabilities of conventional computers. One of…
