Query: Photon-mediated entanglement scheme between a ZnO semiconductor defect
  and a trapped Yb ion   We propose an optical scheme to generate an entangled state between a trapped
ion and a solid state donor qubit through which-path erasure of identical
photons emitted from the two systems. The proposed scheme leverages the similar
transition frequencies between In donor bound excitons in ZnO and the
$^2P_{1/2}$ to $^2S_{1/2}$ transition in Yb$^+$. The lifetime of the relevant
ionic state is longer than that of the ZnO system by a factor of 6, leading to
a mismatch in the temporal profiles of emitted photons. A detuned
cavity-assisted Raman scheme weakly excites the donor with a shaped laser pulse
to generate photons with 0.99 temporal overlap to the Yb$^+$ emission and
partially shift the emission of the defect toward the Yb$^+$ transition. The
remaining photon shift is accomplished via the dc Stark effect. We show that an
entanglement rate of 21 kHz and entanglement fidelity of 94 % can be attained
using a weak excitation scheme with reasonable parameters.
