Experimental Characterization and Modeling of Measurement-Induced State-Transitions in a Fluxonium Superconducting Qubit
Martijn F. S. Zwanenburg, Jinlun Hu, Eugene Y. Huang +3
Superconducting qubits are most often measured using dispersive readout, which, ideally, implements a projective quantum non-demolition (QND) measurement. While a larger readout dr…
Fast microwave-driven two-qubit gates between fluxonium qubits with a transmon coupler
Siddharth Singh, Eugene Y. Huang, Jinlun Hu +6
Two qubit gates constitute fundamental building blocks in the realization of large-scale quantum devices. Using superconducting circuits, two-qubit gates have previously been imple…
Single-Qubit Gates Beyond the Rotating-Wave Approximation for Strongly Anharmonic Low-Frequency Qubits
Martijn F. S. Zwanenburg, Siddharth Singh, Eugene Y. Huang +5
Single-qubit gates are in many quantum platforms applied using a linear drive resonant with the qubit transition frequency which is often theoretically described within the rotatin…
Mixed spin-boson coupling for qubit readout with suppressed residual shot-noise dephasing
Jinlun Hu, Antonio L. R. Manesco, André Melo +3
Direct dipole coupling between a two-level system and a bosonic mode describes the interactions present in a wide range of physical platforms. In this work, we study a coupling tha…
Energy participation ratio analysis for very anharmonic superconducting circuits
Figen Yilmaz, Siddharth Singh, Martijn F. S. Zwanenburg +3
Superconducting circuits are being employed for large-scale quantum devices, and a pertinent challenge is to perform accurate numerical simulations of device parameters. One of the…
