Ultrafast spin dynamics and control in single quantum emitters (Conference Presentation)
Author(s): Denis V. Seletskiy; Christian Traum; Alfred Leitenstorfer

Paper Abstract

Reliable storage and manipulation of spin coherence is at the heart of quantum information processors. Isolated singly-charged semiconductor quantum dots (QDs) are typically characterized by bright ground state emission and hold promise as efficient spin-to-photon interfaces. Ultrafast interactions in condensed phase could enable high-bandwidth information processors, with an additional possibility to engineer quantum properties of light on sub-picosecond timescales. Toward these goals, we employ multi-color femtosecond write and readout pulses to analyze intrinsic spin dynamics in isolated singly-charged epitaxial CdSe/ZnSe QDs. With this we demonstrate control over single-photon-added amplification as well trion quatnum beats, arising from long intraband coherence.
