Purcell enhanced and blinking free single photons from InAs/GaAs quantum dots in deterministically placed circular Bragg gratings

Peter Gschwandtner, Quirin Buchinger, Krishna Chand Maurya +11

The development of efficient, deterministic, and tunable single-photon sources is a cornerstone for the realization of long-distance quantum communication, quantum repeaters, and p…

Experimental measurement of the reappearance of Rabi rotations in semiconductor quantum dots

L. Hanschke, T. K. Bracht, E. Schöll +11

Phonons in solid-state quantum emitters play a crucial role in their performance as photon sources in quantum technology. For resonant driving, phonons dampen the Rabi oscillations…

Coherent driving of direct and indirect excitons in a quantum dot molecule

Frederik Bopp, Johannes Schall, Nikolai Bart +13

Quantum dot molecules (QDMs) are one of the few quantum light sources that promise deterministic generation of one- and two-dimensional photonic graph states. The proposed protocol…
