Photon blockade:
This work proposes a configuration to realize a photon blockade, i.e. a device allowing the propagation of only one photon at a time. (pdf file)

Photon up-conversion:
Here, a device is demonstrated where the optical recombination of a spatially separated population of electrons and holes is controlled with a mid-infrared light. (pdf file)

Relaxation path engineering:
We show here that a careful design of the band structure affords the control of the relaxation path of electrons and holes in double quantum well structures. (pdf file)

Electron teleportation:
An electron population in a double quantum well structure can be optically tranfered between the two wells in a coherent way, without occupying the space in between. (pdf file)
