Query: Biexciton state preparation in a quantum dot via adiabatic rapid
  passage: comparison between two control protocols and impact of
  phonon-induced dephasing   We investigate theoretically under which conditions a stable and
high-fidelity preparation of the biexciton state in a quantum dot can be
realized by means of adiabatic rapid passage in the presence of acoustic phonon
coupling. Our analysis is based on a numerically complete real-time path
integral approach and comprises different schemes of optical driving using
frequency-swept (chirped) pulses. We show that depending on the size of the
biexciton binding energy, resonant two-photon excitations or two-color schemes
can be favorable. It is demonstrated that the carrier-phonon interaction
strongly affects the efficiency of the protocols and that a robust preparation
of the biexciton is restricted to positive chirps and low temperatures. A
considerable increase of the biexciton yield can be achieved realizing
temperatures below 4 K.
