我们讨论了一种方法来创建一个光子数分辨探测器使用巨克尔非线性电磁感应透明的问题。我们的方案可以实现光子数量子非破坏测量与高效率（类似于99%）使用不到1600个原子嵌入在介质波导。
We discuss an 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-nondemolition measurement with high efficiency (similar to 99%) using fewer than 1600 atoms embedded in a dielectric waveguide.
