- Abstract: We propose a scalable design for a spin-photon interface to a color center in
a diamond microdisk. The design consists of a silicon oxynitride hexagonal
lattice overlaid on a diamond microdisk to enable vertical emission from the
microdisk into low-numerical aperture modes, with quantum efficiencies as high
as 45\% for a tin vacancy (SnV) center. Our design is robust to manufacturing
errors, potentially enabling large scale fabrication of quantum emitters
coupled to optical collection modes. We also introduce a novel approach for
optimizing the free space performance of a complex structure using a dipole
model, achieving comparable results to full-wave finite difference time domain
simulations with a 650,000 times reduction in computational time.

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.
