About the first one:
"it has been possible for the first time to trap single atoms with a single-photon strength laser field. "
single photon strength not a single photon ,I already said a single photon laser was possible.And also:
"Pictured is part of this experiment - a cesium MOT dropping onto a high-finesse cavity"
it dosnt say its a photon???
"Far off-resonant traps: a tool for confining atoms in cavities "
The experiment was to trap an atom in a cavity not to bpunce a single photon in an enclosed space to measure how long it took to get to the mirror.

"An efficient source of single photons is thus in demand. A single photon turnstile device is such a source. On this page you can read about recent experimental demonstration of a single photon turnstile device in our group. You may also check out more pictures from a recent talk about this device"
"The current that flows in this situation was measured to be locked to integer multiples of the modulation frequency. This gives further evidence for regulated single photon emission."
"Evidence", "experimenta"l, "thus in demand"....it dosnt look very convincing?
