• Abstract summary: Tin-vacancy centers in diamond are promising spin-photon interfaces owing to their high quantum-efficiency. We report the generation of single photons with $99.7+0.3_-2.5%$ purity and $63(9)%$ indistinguishability from a resonantly excited tin-vacancy center.

• Abstract: Tin-vacancy centers in diamond are promising spin-photon interfaces owing to their high quantum-efficiency, large Debye-Waller factor, and compatibility with photonic nanostructuring. Benchmarking their single-photon indistinguishability is a key challenge for future applications. Here, we report the generation of single photons with $99.7^{+0.3}_{-2.5}\%$ purity and $63(9)\%$ indistinguishability from a resonantly excited tin-vacancy center in a single-mode waveguide. We obtain quantum control of the optical transition with $1.71(1)$-ns-long $\pi$-pulses of $77.1(8)\%$ fidelity. A modest Purcell enhancement factor of 12 would enhance the indistinguishability to $95$\%. The greater than $100$ ms spectral stability shown would then enable strings of up to $10^6$ identical photons to be generated.

• Simultaneously enhancing brightness and purity of WSe$_2$ single photon emitter using high-aspect-ratio nanopillar array on metal [0.18846515534317265]
  Single photon emitters reported to date often fall short of the perceived requirement for such applications. These emitters exhibit excellent purity (even at high emission rates) and improved out-coupling due to the use of a gold back reflector that quenches emission away from the nanopillar.

  No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory. Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons. This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.
