Quantum computers could one day provide computation capabilities beyond what is possible with today’s classical digital computers. We are experimentally investigating quantum computing using qubits based on the spin of holes bound to acceptor impurities in silicon using the successful circuit quantum electrodynamics (cQED) architecture. These qubits have recently been shown to have ultra-long coherence times and possess electric quadrupoles for qubit manipulation and coupling. Together in an industrially relevant silicon-based platform this makes them natural candidates for building large-scale universal quantum computers.
