摘要： We propose a scheme to effectively generate a four-photon path-entangled number state [the NOON state i.e. $\dfrac{1}{\sqrt{2}}(\vert N,0\rangle+\vert 0,N\rangle)$] for the demonstration of four-photon de Broglie wavelength. Our scheme requires only linear optical elements, photon detectors and post-selections which are all within the reach of current technology.
