We present here an all-optical scheme for the experimental realization of a quantum phase gate. It is based on the polarization degree of freedom of two traveling single-photon wave packets and exploits giant Kerr nonlinearities that can be attained in coherently driven ultracold atomic media.
我们在此展示一种用于量子相位门实验实现的全光方案。它基于两个传播的单光子波包的偏振自由度,并利用了在相干驱动的超冷原子介质中可实现的巨大克尔非线性效应。
