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…
