As the field of solid-state quantum engineering matures, it is increasingly necessary to produce quantum emitters with narrow optical transitions and long spin coherence times aligned to nanophotonic structures [1]. The nitrogen-vacancy (NV) defect center in diamond is a well-suited candidate owing to a spin ground state with a long coherence time [2], nearby nuclear spins for quantum memories [3], and spin-selective optical transitions allowing for efficient optical spin initialization and readout [4].

Electrical Tuning of Tin-Vacancy Centers in Diamond

Many applications in quantum information processing require multiple, identical quantum emitters. Among various color centers in diamond, tin-vacancy centers draw attention because of their high quantum efficiency and long spin coherence. The authors study the shifts of optical-transition frequencies of these centers in an applied electric field, and importantly find that both the linear and quadratic coefficients are orders of magnitude smaller than those of non-inversion-symmetric defects such as nitrogen-vacancy centers. This low susceptibility allows the integration of tin-vacancy centers into photonic nanostructures, which is essential for efficient spin-photon interfaces.

Laser-written waveguide-integrated coherent spins in diamond

Quantum emitters, such as the negatively charged nitrogen-vacancy center in diamond, are attractive for quantum technologies, such as nano-sensing, quantum information processing, and as a non-classical light source. However, it is still challenging to position individual emitters in photonic structures while preserving the spin coherence properties of the defect. In this paper, we investigate single and ensemble waveguide-integrated nitrogen-vacancy centers in diamond fabricated by femtosecond laser writing followed by thermal annealing. Their spin coherence properties are systematically investigated and are shown to be comparable to native nitrogen-vacancy centers in diamond. This method paves the way for the fabrication of coherent spins integrated within photonic devices.
