- Abstract summary: We report the narrow inhomogeneous distribution of the zero-phonon line from tin-vacancy (SnV) centers in diamond.
Photoluminescence excitation spectroscopy measurements at a cryogenic temperature showed that SnV centers exhibit stable fluorescence and linewidths close to the Fourier transform-limited linewidth.

- Abstract: We report the narrow inhomogeneous distribution of the zero-phonon line from
tin-vacancy (SnV) centers in diamond and the overlap of spectra from multiple
separated SnV centers. Photoluminescence excitation spectroscopy measurements
at a cryogenic temperature showed that SnV centers exhibit stable fluorescence
and linewidths close to the Fourier transform-limited linewidth. The
inhomogeneous distribution was as low as ~4 GHz, which enabled the observation
of Sn isotope-dependent resonant frequencies. Owing to the narrow inhomogeneous
distribution, we observed multiple SnV centers showing identical photons with
almost the same wavelength and linewidth. Identical SnV centers were also
observed even in different diamond samples, confirming the reliable fabrication
of the high-quality SnV centers.

We report the coherent optical property of a single negatively-charged lead-vacancy center in diamond.
Photoluminescence excitation measurements reveal stable fluorescence with a linewidth of 39 MHz at 6 K, close to the transform-limit estimated from the lifetime measurement.
Due to the suppressed phonon absorption in the PbV center, we observe nearly transform-limited photon emission up to 16 K, demonstrating its high temperature compared to other color centers in diamond.

We investigate the bistability in a small Fabry-Perot interferometer (FPI) with the optical wavelength size cavity, the nonlinear Kerr medium and only a few photons, on average, excited by the external quantum field.
Multiple stationary states of the FPI cavity field with different spectra are possible at realistic conditions, for example, in the FPI with the photonic crystal cavity and the semiconductor-doped glass nonlinear medium.

spectrally narrow, spin-dependent optical transitions of nitrogen vacancy center defects in diamond can be harnessed for quantum networking applications.
Key to such networking schemes is the generation of indistinguishable photons.
Two challenges limit scalability in such systems: defect-to-defect variations of the optical transition caused by local strain variation, and spectral diffusion of the optical frequencies on repeated measurement caused by photoexcitation of nearby charge traps.

Many applications of nitrogen-vacancy (NV) centers in diamond crucially rely on a spectrally narrow and stable optical zero-phonon line transition.
We apply multi-dimensional coherent spectroscopy to an NV center ensemble in bulk diamond at cryogenic temperatures.
Our spectra reveal thermal dephasing due to quasi-localized vibrational modes as well as ultrafast spectral diffusion on the picosecond timescale.

Quantum emitters in hexagonal Boron Nitride (hBN) were recently reported to hol a homogeneous linewidth according to the Fourier-Transform limit up to room temperature.
This unusual observation was traced back to decoupling from in-plane phonon modes which can arise if the emitter is located between two planes of the hBN host material.
