Desafios e Oportunidades rumo à Internet Quântica

Abstract: To exchange data over long distances, in topologically complex networks built on heterogeneous technologies and managed by independent organizations, methods that allow quantum protocols to transparently connect to the underlying hardware implementations are required. However, quantum signals are fragile and cannot be copied or amplified. Until today, just some preliminary versions of network stacks for a quantum internet have been proposed, and only a few basic elements have been suggested. To fully realize the potentials of quantum communication, new challenges and open issues need to be addressed. This paper presents key challenges to enabling a quantum Internet and discusses possible alternatives that are being developed.
