The Silicon Quantum Hardware Program, led by Professor Andrea Morello based at UNSW Sydney, invents, develops and implements novel methods to realize the hardware of a silicon quantum computer with ion-implanted donors in silicon, using fabrication methods compatible with standard industrial processes.

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.
