Laser driving of quantum emitters using engineered optical pulses

Optimal quantum control (OQC) enabled by femtosecond laser pulse shaping techniques provides a highly flexible approach to quantum states manipulation in solid-state qubit systems. Here we apply OQC to optimize the form of the triggering laser pulse for a single photon source. The use of a frequency-swept laser pulse possessing a notch resonant with the transition energy of the quantum emitter enables the spectral isolation of the emitted photon stream in conjunction with resonant driving for good indistinguishability. We show that the robustness of this scheme would enable spectral multiplexing of quantum light sources using a single triggering laser pulse.
