Tailoring Quantum-Correlated Two-Photon Transitions to Excitons in Semiconductor Quantum Wells
David Guzmán, Luis J. Salazar, Ferney J. Rodríguez, Luis Quiroga · 2012
Dependence of excitonic two-photon absorption on the quantum correlations of exciting biphotons in a semiconductor quantum well is studied. We found that exciton oscillator strengths increase when photons arrive simultaneously in entangled states.
