OXFORD SUPERCONDUCTING CIRCUITS RESEARCH GROUP
ABOUT
We are an academic research group at the University of Oxford working on the physics of superconducting circuits and their application to quantum computing.
TOPICS
1
Develop off-chip wiring solutions for scalable superconducting quantum ciruits
Superconducting circuits have emerged as a leading platform for quantum computing development. To achieve practical utility, we require architectures that integrate extensive qubit arrays while maintaining selective qubit control and readout without sacrificing coherence. We are developing a coaxial circuit QED architecture where the qubit and resonator are fabricated on opposite sides of a single chip. Control and readout of the qubits are facilitated by coaxial wiring that runs perpendicular to the chip's plane.

Utilising novel microwave filtering techniques for improved performance in superconducting quantum devices.
Current superconducting quantum computers face space constraints due to dense wiring and large microwave components within dilution refrigerators. These elements manage control signals, filter frequency bands, and safeguard quantum processors from interference. It's imperative to innovate miniature, cost-effective, and efficient microwave technologies. This project aims to modernize microwave techniques for quantum computing, optimizing performance while minimizing hardware and thermal demands, ultimately advancing towards a more practical quantum computing stage.
