我们使用电磁诱导透明(EIT)实现了对高激发里德堡态(高达n=124)的相干光学探测，提供了对里德堡能级的直接无损探测。我们发现EIT谱允许直接光学探测气相中的电场瞬变，并且我们将对ND系列的精细结构分裂的测量扩展到n=96。通过EIT实现里德堡态的相干耦合也可用于交叉相位调制和光子纠缠。
We demonstrate coherent optical detection of highly excited Rydberg states (up to n=124) using electromagnetically induced transparency (EIT), providing a direct nondestructive probe of Rydberg energy levels. We show that the EIT spectra allow direct optical detection of electric field transients in the gas phase, and we extend measurements of the fine structure splitting of the nd series up to n=96. Coherent coupling of Rydberg states via EIT could also be used for cross-phase modulation and photon entanglement.
