What Charles Adams and colleagues at Durham University have now done is come up with a way of storing individual optical photons in highly excited states of an atomic gas. Once stored, the photons can be made to interact strongly, before being released again. An important feature of the technique is that it uses microwaves, which are also used to control some types of stationary qubit.
Apparently, this is to be published in PRL.
Definitely a commendable accomplishment here in the evolution of our capability of using photons for quantum communications.
