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…

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…
