Observing the dynamics of photon bound states using a single quantum dot

Photon bound states are quantum states of light that emerge in systems with ultrahigh optical non-linearities. A single artificial atom was used to study the dynamics of these states, revealing that the number of photons within the pulse determines the time delay after the pulse scatters off the atom.
