VLSI quantum computer in diamond

Abstract

We discuss how Very Large Scale Integration (VLSI) fabrication techniques can be used to build scalable solid-state quantum computers in diamond with either room temperature operation, or low temperature operation with photonic control. For this discussion we consider nitrogen-vacancy (NV) color centers where the qubits are electron and/or nuclear spins. To achieve scalability the NV centers are placed in well-defined locations using ion implantation, and are controlled using optical and/or microwave excitation as well as localized static electric and/or magnetic fields.
