Suppression of Phonon-mediated Decoherence in Telecom-Compatible Semiconductor Quantum Emitters

We report the demonstration of adiabatic rapid passage on single solid-state quantum emitters based on semiconductor quantum dots. By extending our earlier experiments employing femtosecond pulse shaping for rapid and arbitrary qubit rotations to the strong-driving regime, we demonstrate full suppression of decoherence tied to LA phonon coupling. Our results will support the development of single photon sources and distributed quantum networks using semiconductor quantum dots.
