Quantum Computing and Information Processing: In our experiments, we use superconducting qubits, which can be manipulated on short time scales with respect to their coherence times within a cryogenic environment. Thanks to the relatively simple and reliable fabrication there exists a clear path towards a scalable architecture to realize the building blocks of a future quantum computer.
Physical Review Applied
Abstract: State-of-the-art single-qubit gates on superconducting transmon qubits can achieve the fidelities required for error-corrected computations; however, parameter fluctuations due to qubit instabilities,…
Communications Materials
Abstract: One main limiting factor towards achieving high coherence times in superconducting circuits is two-level system (TLS) losses. Mitigating such losses requires controlling the formation of native oxides…
Physical Review Applied
Abstract: Scaling up superconducting quantum processors necessitates the use of a high routing density for readout and control lines, relying on low-loss interconnects to maintain design flexibility and device…
IEEE Transactions on Microwave Theory and Techniques
Abstract: Fast and high-fidelity qubit readout requires strong coupling between the readout resonator and the feedline. However, such coupling unavoidably enhances qubit decay through the Purcell effect. We…
