Design and Operation of Wafer-Scale Packages Containing >500 Superconducting Qubits
Oscar W. Kennedy, Waqas Ahmad, Robert Armstrong +14
Packages capable of supporting large arrays of high-coherence superconducting qubits are vital for the realisation of fault-tolerant quantum computers and the necessary high-throug…
Analysis of Josephson Junction Barrier Variation: A Combined Electron Microscopy, Breakdown and Monte-Carlo Approach
Oscar W. Kennedy, Kevin G. Crawford, Kowsar Shahbazi +1
Josephson junctions manufactured to tight tolerances are necessary components for superconducting quantum computing. Developing precise manufacturing techniques for Josephson junct…
Integration of through-sapphire substrate machining with superconducting quantum processors
Narendra Acharya, Robert Armstrong, Yashwanth Balaji +7
We demonstrate a sapphire machining process integrated with intermediate-scale quantum processors. The process allows through-substrate electrical connections, necessary for low-fr…
Electron-beam annealing of Josephson junctions for frequency tuning of quantum processors
Yashwanth Balaji, Narendra Acharya, Robert Armstrong +7
Superconducting qubits are a promising route to achieving large-scale quantum computers. A key challenge in realising large-scale superconducting quantum processors involves mitiga…
Domain Wall Motion and Interfacial Dzyaloshinskii-Moriya Interactions in Pt/Co/Ir/Ta Multilayers
Kowsar Shahbazi, Joo-Von Kim, Hans T. Nembach +6
The interfacial Dzyaloshinskii-Moriya interaction (DMI) is important for chiral domain walls (DWs) and for stabilizing magnetic skyrmions. We study the effects of introducing incre…
Magnetic properties and field-driven dynamics of chiral domain walls in epitaxial Pt/Co/AuPt trilayers
Kowsar Shahbazi, Aleš Hrabec, Simone Moretti +5
Chiral domain walls in ultrathin perpendicularly magnetised layers have a Néel structure stabilised by a Dzyaloshinskii-Moriya interaction (DMI) that is generated at the interface…
Role of phonon skew scattering in the spin Hall effect of platinum
G. V. Karnad, C. Gorini, K. Lee +11
We measure and analyze the effective spin Hall angle of platinum in the low residual resistivity regime by second harmonic measurements of the spin-orbit torques for a multilayer o…
Discrete Hall resistivity contribution from Néel skyrmions in multilayer nanodiscs
Katharina Zeissler, Simone Finizio, Kowsar Shahbazi +10
Magnetic skyrmions are knot-like quasiparticles. They are candidates for non-volatile data storage in which information is moved between fixed read and write terminals. Read-out op…
