Analytic leakage suppression with a single control field: fast two-qubit gates with tunable couplers
Lukas Heunisch, Michael J. Hartmann, Aashish A. Clerk
Simple analytic pulse-shaping techniques are of great practical utility in quantum control, with prime examples being the DRAG method for suppressing leakage in superconducting mic…
Quantum gates with parametrically driven multi-qubit couplers
Verena Feulner, Marjan Fani, Lukas Heunisch +2
Superconducting quantum processors could significantly profit from enhanced connectivity together with precise control of interactions and gates between qubits. Here we investigate…
Scalable Fluxonium-Transmon Architecture for Error Corrected Quantum Processors
Lukas Heunisch, Longxiang Huang, Stephan Tasler +9
We propose a hybrid quantum computing architecture composed of alternating fluxonium and transmon qubits, that are coupled via transmon tunable couplers. We show that this system o…
Optimizing Superconducting Three-Qubit Gates for Surface-Code Error Correction
Stephan Tasler, Josias Old, Lukas Heunisch +4
Quantum error correction (QEC) is one of the crucial building blocks for developing quantum computers that have significant potential for reaching a quantum advantage in applicatio…
Cross-talk in superconducting qubit lattices with tunable couplers -- comparing transmon and fluxonium architectures
F. Lange, L. Heunisch, H. Fehske +2
Cross-talk between qubits is one of the main challenges for scaling superconducting quantum processors. Here, we use the density-matrix renormalization-group to numerically analyze…
Tunable coupler to fully decouple and maximally localize superconducting qubits
Lukas Heunisch, Christopher Eichler, Michael J. Hartmann
Enhancing the capabilities of superconducting quantum hardware, requires higher gate fidelities and lower crosstalk, particularly in larger scale devices, in which qubits are coupl…
