| Abstract: | 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. |
