Aim

The project explores new ways to connect and control quantum bits (qubits) over long distances within semiconductor quantum devices. We aim to study extended-range exchange interactions in spin qubits and use these discoveries to demonstrate a two-dimensional qubit architecture that enables quantum error correction and cancellation. Achieving reliable qubit manipulation through long-range coupling in a silicon-compatible platform would mark a major step toward scalable quantum processors with millions of interconnected qubits on a single chip.

To realise this vision, we will develop hole spin qubits in novel high-mobility cs-GoS structures and explore mesoscopic effects that can mediate and enhance long-range exchange coupling between qubits. These efforts aim to establish a new paradigm for scalable, high-fidelity quantum information processing.
