Photonic Crystals in Diamond for Quantum Information Technology
One of the approaches to realize entanglement for quantum information processing, is cavity quantum effectrodynamics. In this approach, the interaction of material qubits (atomic or effectronic quantum states) with a high finesse optical resonator is used for atom-atom, atomphoton, or photon-photon entanglement. The main challenge in this approach is to avoid decoherence induced by the cavity modes that leak to the environment. An attractive architecture to overcome this obstacle is formed by high-Q, coupled nano-cavities in a Photonic Crystal. The coupling of the nano-cavities can be gated to avoid de-coherence. The nitrogen-vacancy (NV) deffect center in diamond, was recently shown to allow successful measurement of its spin quantum state, thus becoming a strong candidate for solid state quantum information processing. Our initial findings on diamond-based, photonic crystal coupled cavity studies, and preliminary fabrication experiments are encouraging, leading to the possibility to demonstrate a gated qubit in a diamond-based photonic crystal cavity.
