摘要

We discuss a novel approach to the problem of creating a photon number resolving detector using the giant Kerr nonlinearities available in electromagnetically induced transparency. Our scheme can implement a photon number quantum non-demolition measurement with high efficiency ( $\sim$ 99%) using less than 1600 atoms embedded in a dielectric waveguide.
