As superconducting quantum circuits scale to larger sizes, the problem of frequency
crowding proves a formidable task. Here we present a solution for this problem in fixed …

Scaling the number of qubits while maintaining high-fidelity quantum gates remains a key
challenge for quantum computing. Presently, superconducting quantum processors with> 50 …

We investigate die-level and wafer-scale uniformity of Dolan-bridge and bridgeless
Manhattan-style Josephson junctions, using multiple substrates with and without through …

Abstract Reproducibility of Al/AlOx/Al Josephson junctions is a challenge for scaling up
superconducting quantum processors. The frequency uncertainty of the transmon qubits …

We propose and analyze two types of microwave-activated gates between a fluxonium and
a transmon qubit, namely a cross-resonance (CR) and a CPHASE gate. The large frequency …

Superconducting qubits based on Al/AlOx/Al Josephson junction are one of the most
promising candidates for the physical implementation of universal quantum computers. Due …

Quantum computing is a consequence of the ever increasing demand to tackle complex
problems, while drastically reducing the computation time compared to classical computers …

In this thesis variations in the Josephson junction conductance across a 100 mm wafer are
studied. For this study junctions fabricated with a Dolan bridge and with the Manhattan …
