Large Scale Type II Quantum Computing in NV-Diamond Using PBG-Based Cavities

Abstract

Experimentally, our key accomplishment to date has been the demonstration of alignment of spins (i.e., the individual qubits) in NV-Diamond. Essentially, this represents our ability to initialize all the qubits into their individual (i.e., uncoupled) true ground states, as well as the ability to perform single qubit operations on a collective scale. Furthermore, we have derived the explicit quantum circuits and algorithms necessary for performing the multi-qubit operations, necessary for realizing a quantum computer. These circuits require the realization of low-loss, small volume, highQ cavities. We have used FDTD codes to design such a cavity--- in two dimensions---for NV-Diamond. We have also incorporated the cavity-QED equations describing the interplay between optically active color centers and a single photon, in order to optimize the key performance parameter: the number of QC operations that can be performed before decoherence.
