Polarization qubit phase gate in driven atomic media
arXiv:quant-ph/0302070 · doi:10.1103/PhysRevLett.90.197902
Abstract
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 travelling single photon wave-packets and exploits giant Kerr nonlinearities that can be attained in coherently driven ultracold atomic media.
