Coherent Control of Quantum-Dot Spins with Cyclic Optical Transitions
Zhe Xian Koong, Urs Haeusler, Jan M. Kaspari +14
Solid-state spins are promising as interfaces from stationary qubits to single photons for quantum communication technologies. Semiconductor quantum dots have excellent optical coh…
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…
Quantum beats of exciton-polarons in CsPbI3 perovskite nanocrystals
A. V. Trifonov, M. O. Nestoklon, M. -A. Hollberg +10
Exciton-phonon interactions govern the energy level spectrum and thus the optical response in semiconductors. In this respect, lead-halide perovskite nanocrystals represent a uniqu…
Few-Photon SUPER: Quantum emitter inversion via two off-resonant photon modes
Quentin W. Richter, Jan M. Kaspari, Thomas K. Bracht +4
With the realization of controlled quantum systems, exploring excitations beyond the resonant case opens new possibilities. We investigate an extended Jaynes-Cummings model where t…
