Quantum Networking at the Speed of Quantum Computation: Kilohertz Entanglement in a Heterogeneous Quantum System
Researchers report entangling a trapped barium-138 ion with a silicon-vacancy centre, reaching kilohertz entanglement rates over a photonic link. The work targets distributed quantum computing by connecting qubits in separate processor modules. The result addresses the photon-loss bottleneck that has limited entanglement rates between different matter qubits.

Within two years, this kilohertz ion–colour-centre entanglement link could be integrated into a two-node demonstration in which a trapped-ion processor performs a distributed quantum gate with a silicon-vacancy memory qubit.
The reported rate removes photon loss as the dominant waiting-time bottleneck for a single link; if the entanglement fidelity survives integration with existing ion-trap and diamond nanophotonic control systems, a small modular network becomes an engineering target rather than a physics demonstration.
