We present the first experimental realization of a flexible multidimensional quantum channel where the Hilbert space dimensionality can be controlled electronically. Using electro-optical modulators (EOM) and narrow-band optical filters, quantum information is encoded and decoded in the temporal degrees of freedom of photons from a long-coherence-time single-photon source. Our results demonstrate the feasibility of a generic scheme for encoding and transmitting multidimensional quantum information over the existing fiber-optical telecommunications infrastructure.

    A temporal-mode extension of the LM05 quantum protocol encodes symbols as bit flips on light pulses, but loss, errors, and the need to encrypt the ordering limit complete recovery to sub-kilometer distances.
