TL;DR: Remarkably, coherent control occurs even under room temperature conditions and enables to directly resolve the dephasing times, which may open a new way for the realization of room temperature semiconductor-based ultra-high speed quantum processors with all the advantages of upscaling and low-cost manufacturing.
Abstract: The coherence time during which two energetic states in a semiconductor are synchronized can be very short. Here, the authors demonstrate that despite their brief coherence times, coherent control of such states can be achieved at room temperature.

Abstract: A unique experimental setup combining short pulse pump-probe and FROG characterization, enables control by light pulses over the electronic quantum state, and a direct observation of the wavefunction decoherence in a room-temperature semiconductor laser amplifier.
