  • All-optical coherent control schemes offer well-localized and ultrafast control of individual qubits in many-qubit systems. Here the authors report on all-optical resonant and Raman-based control of single silicon vacancies using picosecond pulses, much faster than the ground state coherence time.

  • Heralded entanglement between two independently trapped single rubidium atoms is generated over long telecom fibre links using quantum frequency conversion in an important step towards the realization of large-scale quantum network links.

  • Entanglement between photons and stationary quantum nodes is a fundamental resource for quantum communication, but typical transition wavelengths are far from the telecom band. Here, the authors deal with the problem using polarisation-independent, entanglement-preserving frequency conversion.

  • Optical microcavities have been fabricated in single-crystal diamond and tuned into resonance with the zero phonon line of an ensemble of silicon-vacancy colour centres, which results in an enhancement of spontaneous emission.
