Quantum communication allows us to solve tasks that are provably
impossible using classical communication. A famous example is quantum
key distribution which enables secure communication. Here, security can
directly be traced back to fundamental properties of quantum
entanglement, and is guaranteed even if an eavesdropper holds a quantum
computer now or in the future. Many other applications have already been
identified ranging from solving clock synchronization, to exotic
applications such as extending the baseline of telescopes to make better
observations.

In this talk, we will give an overview of the state of the art of
quantum communication, and look at how quantum entanglement might help
us to solve cryptographic problems. We continue to look ahead to some of
the many challenges to be solved in order to realize large scale quantum
networks, which may eventually allow us to create entanglement between
any two points on earth yielding new insights to physics, and bringing
entirely new internet applications.
