Cross-talk in superconducting qubit lattices with tunable couplers -- comparing transmon and fluxonium architectures
F. Lange, L. Heunisch, H. Fehske +2
Cross-talk between qubits is one of the main challenges for scaling superconducting quantum processors. Here, we use the density-matrix renormalization-group to numerically analyze…
Observation of Josephson Harmonics in Tunnel Junctions
Dennis Willsch, Dennis Rieger, Patrick Winkel +27
Approaches to developing large-scale superconducting quantum processors must cope with the numerous microscopic degrees of freedom that are ubiquitous in solid-state devices. State…
Perturbative power series for block diagonalisation of Hermitian matrices
Ishan N. H. Mankodi, David P. DiVincenzo
Block diagonalisation of matrices by canonical transformation is important in various fields of physics. Such diagonalization is currently of interest in condensed matter physics,…
g-factor symmetry and topology in semiconductor band states
Mira Sharma, David P. DiVincenzo
The tensor, which determines the reaction of Kramers-degenerate states to an applied magnetic field, is of increasing importance in the current design of spin qubits. It i…
