Abstract

We report our recent experimental demonstration of a KLM CNOT gate[1], a photonic quantum circuit to combine two efficient artificial nonlinear elements. This experimental demonstration[2] confirms the first step in the KLM recipe for all-optical quantum computation, and should be useful for on-demand entanglement generation and purification. We will also report our activities toward the realization of nonlinear sign shift gate using diamond nano-crystals coupled to a microsphere cavity[3].
