Ronald Hanson's group at QuTech is a reference experimental laboratory for nitrogen-vacancy (NV) centre quantum networking, with a track record of "firsts" in heralded solid-state entanglement, loophole-free Bell tests, three-node NV networks, and most recently a 25 km Delft–The Hague link over deployed telecom fibre. Current work extends NV memory coherence, telecom-band frequency conversion, and multi-node protocol stacks, and pursues group-IV colour centres (SiV, tin-vacancy) as longer-coherence successors to NV. Specific demonstrations are listed in milestones.
Current focus: Diamond-spin quantum systems for a quantum internet — Per the lab's own framing (qutech.nl/lab/hanson-lab): exploiting the properties of spins in diamond to study and engineer interactions between individual quantum systems, with the long-term goal of building a quantum computer and realising a quantum internet.
