Abstract
To increase the performance of quantum computers and set up long-distance quantum communication networks, it is essential to develop interfaces linking stationary qubits to flying qubits. This lecture will present the main approaches being explored to design such interfaces, whether by coupling a qubit - atom, spin, superconducting qubit... - to light or acoustic waves. We'll also take the opportunity to introduce the field of quantum memories, discussing the metrics used to characterize them as well as recent achievements. Finally, we will offer an overview of the applications made possible by these quantum interfaces and memories.
