Title
Quantum networking with trapped ions: two things to do with two qubits two metres apart
Abstract
I will outline some applications of quantum networking, and describe two recent experiments performed using an elementary two-node network which links two separate ion traps via a single-photon optical fibre interface. In the first experiment, we present the realization of a complete quantum key distribution protocol whose security is guaranteed by Bell’s Theorem. In the second, we show how the network link can be used to entangle a pair of atomic clocks, enabling frequency comparison at the ultimate quantum precision – the Heisenberg limit.
