QuTech, a collaboration between the Technical University of Delft and Dutch research institute TNO, has started a new project with KPN, Dutch research network Surf and OPNT, a spin-off of Laser LaB from the VU University Amsterdam. The project is aimed at connecting different quantum processors over a longer distance in a Dutch network. For example, the partners want to realise the very first fully functional quantum network over fibre.
In a quantum network, quantum processors are connected to each other via optical channels to enable the exchange quantum bits (qubits). Qubits have a number of properties that make them very different from the bits currently in use in classic networks.
Quantum communication networks are expected to eventually develop into a global quantum internet, to enables, among other things, secure communication, position verification, clock synchronization and the performance of calculations on external quantum computers. The project is expected to yield new techniques, insights and protocols that will bring a quantum internet closer.
