- Abstract: The photonic Temporal Mode (TM) represents a possible candidate for the
delivery of viable multidimensional quantum communications. However, relative
to other multidimensional quantum information carriers such as the Orbital
Angular Momentum (OAM), the TM has received less attention. Moreover, in the
context of the emerging quantum internet and satellite-based quantum
communications, the TM has received no attention. In this work, we remedy this
situation by considering the traversal through the satellite-to-Earth channel
of single photons encoded in TM space. Our results indicate that for
anticipated atmospheric conditions the photonic TM offers a promising avenue
for the delivery of high-throughput quantum communications from a satellite to
a terrestrial receiver. In particular, we show how these modes can provide for
improved multiplexing performance and superior quantum key distribution in the
satellite-to-Earth channel, relative to OAM single-photon states. The levels of
TM discrimination that guarantee this outcome are outlined and implications of
our results for the emerging satellite-based quantum internet are discussed.
