Disentangling the Exchange Coupling of Entangled Donors in the Si Quantum Computer Architecture
Disentangling the Exchange Coupling of Entangled Donors in the Si Quantum Computer Architecture
We develop a theory for micro-Raman scattering by single and coupled two-donor states in silicon. We find the Raman spectra to have significant dependence on the donor exchange splitting and the relative spatial positions of the two-donor sites. In particular, we establish a strong correlation between the temperature dependence of …
