Resumé:
The general context of this
thesis project is the vision of the Quantum Internet, which is to provide
fundamentally new technology by enabling quantum communication between any two
points on Earth. Such a Quantum Internet allows the transmission of quantum bits (qubits) over
long distances in order to solve tasks that are provably impossible for any classical
communication network. Possibly the most well-known protocol is quantum key
distribution, which enables secure communication; but, quantum communication is
also known to offer significant advantages for many other tasks such as secure
delegated computation or clock synchronization. Moreover, the ability to
generate entanglement between distant sites provides scientists with a unique
new platform for fundamental studies of nature.
The future Quantum Internet will operate in
parallel to the ‘classical’ internet we know today and in analogy with the
latter will consist of the following subsystems: quantum repeaters, end nodes,
infrastructure technology, control and applications. From a network
point of view, it will be necessary to develop an efficient quantum network stack that allows fast
and reactive decisions in controlling the network and delivering qubits to the
right destination, in order to mitigate the effect of limited quantum memory
lifetimes. This stack should also enable the realization of any application supported by the end nodes, as well
as the seamless integration of quantum network tools and applications in
existing environments.
In this thesis project, we propose to study
multiple aspects of the Quantum Internet, including in particular the design
and optimization of algorithms for routing of the quantum resources in the
network; the development of building blocks of the network stack adapted to
current infrastructures; the assessment of network operation using realistic
experimental parameters for the physical resources (quantum repeaters, end
nodes, quantum memories, photonic sources) and for the communications channels;
and the design of new protocols for quantum networks. These are all aspects
that are crucial for building the future network infrastructures.
