Silicon Quantum Processor with Robust Long-Distance Qubit Couplings

Guilherme will present a scalable design for a silicon quantum processor that exploits the electric dipole induced on a donor with a top-gated structure. Quantum information is encoded in either the nuclear-spin or the flip-flop states of electron and nucleus. The physical qubits are spaced by hundreds of nanometers and coupled through direct electric dipole interactions and/or photonic links. They can be controlled at high-speeds by extremely low-power microwave fields, while still preserving their outstanding coherence times.
