I was going through a paper explaining how the write-in and read-out efficiencies can be increased using cold atoms where they used Rydberg atoms, and mentioned that they were probed using EIT(Electromagnetically Induced Tranparency).
I have a brief idea about EIT, that it can be used to make a system transparent, which would otherwise be opaque.
I also know that the three states are used here, those are
- The ground state
- An excited state
- A rydberg state
Can anyone explain how EIT is used here?
