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…
