摘要:

我们提出了一个简单的方案来扩展偏振纠缠W态。通过在偏振相关分束器(PDBS)上混合一个光子和其中一个处于n光子W态的光子,我们可以在后选择后获得(n+1)光子W态。我们的方案也为利用单光子和线性光学产生n光子W态打开了大门。

英文摘要:

We propose a simple scheme for expanding a polarization-entangled W state. By mixing a single photon and one of the photons in an n-photon W state at a polarization-dependent beam splitter (PDBS), we can obtain an (n+1)-photon W state after post-selection. Our scheme also opens the door for generating n-photon W states using single photons and linear optics.
