Solid-state quantum emitters have emerged as a leading quantum memory for quantum networking applications. However, standard optical characterization techniques are neither efficient nor repeatable at scale. Here we introduce and demonstrate spectroscopic techniques that enable large-scale, automated characterization of colour centres.

- Developing quantum computers requires effectively distributing entanglement among many qubits, and diamond colour centres are promising candidates due to their remote entanglement and coherent control capabilities.
- This research introduces a method to integrate high-yield "quantum microchiplets" made of diamond waveguide arrays into photonic integrated circuits, achieving a defect-free arrangement.
- The study demonstrates that individual colour centre transitions can be finely tuned, allowing for consistent and stable optical performance, which is vital for advancing quantum repeaters and processors.
Solid-state quantum emitters that couple coherent optical transitions to long-lived spin qubits are essential for quantum networks. Here we report on the spin and optical properties of individual tin-vacancy (SnV) centers in diamond nanostructures. Through cryogenic magneto-optical and spin spectroscopy, we verify the inversion-symmetric electronic structure of the SnV, identify spin-conserving and spin-flipping transitions, characterize transition linewidths, measure electron spin lifetimes, and evaluate the spin dephasing time.

The fabrication of non-aggregated and uniformly-sized nanodiamonds with systematic integration of single quantum emitters has so far been lacking. Here, we present a top-down fabrication method to produce 30.
