Quantum environment afterglow from broadband excitation spectroscopy in superconducting qubits
J. R. Guimarães, Y. Liu, Y. Gao +10
Understanding the qubit environment is central to fault-tolerant superconducting quantum computation. Characterization typically relies on relaxation, leaving excitation largely un…
Parametric two-qubit gates via Landau-Zener interference
Simon Geisert, Albert Hertel, Soeren Ihssen +23
We propose and demonstrate gates between two superconducting qubits based on quantum interference of consecutive Landau-Zener (LZ) transitions. This gate mechanism bridges between…
Contactless terahertz mapping of wafer-scale superconducting NbTiN thin films
Yayi Lin, Marc Neis, Marcello Pio Guardascione +9
For large-scale superconducting quantum technology, e.g. quantum computing, the homogeneity of wafer-scale superconducting thin films is vital for consistent performance of the fab…
Simple analytical flux-tuned iSWAP pulses for leakage suppression
Dimitrios Georgiadis, Boxi Li, Asier Galicia +3
Fast, high-fidelity two-qubit gates are a key requirement for fault-tolerant quantum computation. Tunable coupler architectures provide a flexible approach for implementing entangl…
Highly crystalline superconducting TiN resonators grown on thermally reconstructed sapphire
Thomas J. Smart, Marc Neis, Janine Lorenz +15
High quality crystalline growth of a thin film on sapphire requires sufficient substrate preparation, often achieved via the use of aggressive chemical cleaning. Direct thermal rec…
Analytical blueprint for 99.999% fidelity X-gates on present superconducting hardware under strong driving
José Diogo Da Costa Jesus, Boxi Li, Yuan Gao +3
Achieving very fast gates that undercut the natural limits set by decoherence requires going into the strong driving limit. Realizing single-qubit control predicted beyond semi-cla…
Ultrafast Single Qubit Gates through Multi-Photon Transition Removal
Y. Gao, A. Galicia, J. D. Da Costa Jesus +12
One of the main enablers in quantum computing is having qubit control that is precise and fast. However, qubits typically have multilevel structures making them prone to unwanted t…
