Efficient protocols for long-distance quantum communication
In quantum communications, entangled states are considered a 'resource' – something that is costly to produce and that allows the implementation of valuable transformations. A famous resource conversion provided by the quantum teleportation protocol says we can send one qubit with the transmission of a shared entangled pair of qubits (ebit) plus two qubits of classical communication (cbits). Casting quantum protocols in such resource inequalities has proven useful since the algebraic manipulation of inequalities results in new protocols. However, this approach has hitherto been largely limited to point-to-point communication. The goal of the EU-funded RESOURCE Q project is to develop more efficient communication protocols over long distances. Another focus will be on exploiting the connection between entangled states and tensors.
