When three or more levels are simultaneously coupled by light in a charge transfer double quantum well (QW), it is possible to transfer electrons coherently between the QWs. Using two light pulses of different wavelengths, the transient occupation of the space between the two QWs can be made arbitrarily small: electron teleportation. We discuss this phenomenon within a single electron model, estimate the effect of decoherence, and compare our results with experiments.
