Proposed robust and high-fidelity preparation of excitons and biexcitons in semiconductor quantum dots making active use of phonons

M. Glässl, A. M. Barth, V. M. Axt

It is demonstrated how the exciton and the biexciton state of a quantum dot can be prepared with high fidelity on a picosecond time-scale by driving the dot with a strong laser pul…
