Small Quantum Low Density Parity Check Codes for Near-Term Experiments
Christian Kraglund Andersen, Eliška Greplová
It is widely accepted that quantum error correction is essential for realizing large-scale fault-tolerant quantum computing. Recent experiments have demonstrated error correction c…
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…
Calibrating Magnetic Flux Control in Superconducting Circuits by Compensating Distortions on Time Scales from Nanoseconds up to Tens of Microseconds
Christoph Hellings, Nathan Lacroix, Ants Remm +8
Fast tuning of the transition frequency of superconducting qubits using magnetic flux is essential, for example, for realizing high-fidelity two-qubit gates with low leakage or for…
