- Abstract summary: Tin-vacancy centers in diamond exhibit narrow-linewidth emission in nanostructures and possess long spin coherence times at temperatures above 1 K.
We integrate SnV$,textrm-$ centers into one-dimensional photonic crystal resonators and observe a 40-fold increase in emission intensity.
Our results pave the way for the creation of efficient, scalable spin-photon interfaces based on SnV$,textrm-$ centers in diamond.

- Abstract: The realization of quantum networks critically depends on establishing
efficient, coherent light-matter interfaces. Optically active spins in diamond
have emerged as promising quantum nodes based on their spin-selective optical
transitions, long-lived spin ground states, and potential for integration with
nanophotonics. Tin-vacancy (SnV$^{\,\textrm{-}}$) centers in diamond are of
particular interest because they exhibit narrow-linewidth emission in
nanostructures and possess long spin coherence times at temperatures above 1 K.
However, a nanophotonic interface for SnV$^{\,\textrm{-}}$ centers has not yet
been realized. Here, we report cavity enhancement of the emission of
SnV$^{\,\textrm{-}}$ centers in diamond. We integrate SnV$^{\,\textrm{-}}$
centers into one-dimensional photonic crystal resonators and observe a 40-fold
increase in emission intensity. The Purcell factor of the coupled system is 25,
resulting in channeling of the majority of photons ($90\%$) into the cavity
mode. Our results pave the way for the creation of efficient, scalable
spin-photon interfaces based on SnV$^{\,\textrm{-}}$ centers in diamond.

diamond [0.0]
The nitrogen-vacancy center in diamond is an attractive resource for the generation of remote entangled states.
Here, we couple a nitrogen-vacancy center with a narrow extrinsically broadened linewidth, hosted in a micron-thin membrane, to the mode of an open optical microcavity.
The resulting Purcell factor of $sim$1.8 increases the fraction of zero-phonon line photons to above 44%, leading to coherent photon emission rates exceeding four times the state of the art.

spin qubits in a strain-tuned diamond membrane heterostructure [54.501132156894435]
Tin-vacancy center (SnV) in diamond is a promising spin-photon interface with desirable optical and spin properties at 1.7 K.
We introduce a new platform that overcomes these challenges - SnV centers in uniformly strained thin diamond membranes.
The presence of crystal strain suppresses temperature dependent dephasing processes, leading to a considerable improvement of the coherence time up to 223 $mu$s at 4 K.

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.
