The field of Quantum Communications has seen a rapid transition from a theoretical topic at the boundary of Physics and Information Theory, less than a decade ago, to its current status as an applied science, with direct technological, social and economic implications. At the core of Quantum Communications science is the concept of a Quantum Network, a physical infrastructure that permits users to transmit quantum states, aided by shared entanglement, thus facilitating quantum communications.

In parallel with the first implementations of Quantum Networks, the field of Quantum Computation has seen a meteoric rise with IBM’s launch of the first commercially-available quantum computer in 2019, as well as the development of the first generation of Quantum Sensors. These devices produce or take as input quantum states, thus highlighting the need for a robust mechanism of quantum state transfer. Quantum Networks represent a fundamental step in the development of the Quantum Internet, a global network capable of efficient information transfer, in both classical and quantum form, and will act as an additional functional layer, on top of the existing classical network architecture.

In this talk I will highlight three fundamental topics of the Quantum Communications ecosystem: networking problems (such as entanglement routing and entanglement swapping schemes), network predictions (for example on graph states used as a resource for quantum communication) and classical-to-quantum data encoding (as part of the classical-to-quantum communications layer).
