- Silicon Quantum Hardware Program
The Silicon Quantum Hardware Program is led by Professor Andrea Morello based at UNSW Sydney. The research focuses on experimental control, readout and coupling of single P-atom spin qubits in silicon, for the construction of a scalable spin-based quantum computer that is compatible with standard semiconductor fabrication processes. In addition, it invents and develops new theoretical ideas for efficient and scalable quantum logic gates for donors in silicon.
