A structured material is transferred to a substrate. A gas delivery system includes a delivery chamber, a precursor inlet valve, a carrier inlet valve, an outlet valve, and a controller. The print time designation is attached to the first job and the first job is transmitted from the end-user station to a printer. If a pair of channels for transport of quantum data is available within the C-band, then the source of entangled photon pairs is tuned to emit in a pair of channels in the C-band.
