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…

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…

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…

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…
