Towards a Distributed Quantum Computing Ecosystem
share
The Quantum Internet, by enabling quantum communications among remote quantum nodes, is a network capable of supporting functionalities with no direct counterpart in the classical world. Indeed, with the network and communications functionalities provided by the Quantum Internet, remote quantum devices can communicate and cooperate for solving computational tasks by adopting a distributed computing approach. The aim of this paper is to provide the reader with an overview about the Quantum Internet as the fundamental underlying infrastructure for the design and the realization of a distributed quantum computing ecosystem. For this we first introduce the Quantum Internet. Then we present a high-level system abstraction of a distributed quantum computing ecosystem, by describing the constituting layers from a communication engineering perspective. Finally we discuss the challenges connected to the design of the aforementioned layers.
