Crossover from Rabi oscillations to adiabatic population switching in the Faraday optical control of quantum dot spins

Jan M. Kaspari, Zhe Xian Koong, Dorian A. Gangloff +2

Stimulated Raman transitions in Faraday geometry allow for simultaneous single-shot qubit readout and qubit control. It involves driving an unbalanced system via an auxiliary…
