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…
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…
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…
The SpinBus Architecture: Scaling Spin Qubits with Electron Shuttling
Matthias Künne, Alexander Willmes, Max Oberländer +10
Quantum processor architectures must enable scaling to large qubit numbers while providing two-dimensional qubit connectivity and exquisite operation fidelities. For microwave-cont…
