Currently, I am a postdoc researcher in quantum optics at C2N, Paris, working with quantum light sources based on semiconductor quantum dots. These sources allow the production of high-quality quantum light - single or entangled photons - on demand. Being involved in the development of such sources is a unique opportunity to contribute to the development of quantum hardware for the realization of quantum technologies. But not only! It is also a fascinating place to juggle with individual photons and construct unique objects from light!
April 2019 - July 2023: PhD student in Löffler's lab working with single-photon source based on semiconductor quantum dot technology. Experimental and theoretical experience with linear optical photon manipulation, spin physics, quantum light source characterization and designing. Other: supervision of more than 7 bachelor and master students. Research areas: Quantum optics, quantum light sources (single and entangled photons), multi-photon entanglement, semiconductor quantum dots
Within Quantera project CUSPIDOR and under the supervision of a specialist in Density functional theory (DFT) Felipe Murphy-Armando, I studied using DFT (software Abinit) electronic structure modification of SiGe quantum dots induced by implantation of a vacancy and resulting improvement optical activity. This attracted attention to developing quantum emitters based on CMOS-compatible SiGe quantum dots, which are in their pure case poor emitters. Work was published: F. Murphy-Armando, M. Brehm, P. Steindl, et al., Phys. Rev. B 103, 085310 (2021).
I worked as a laboratory assistant on the experimental study of low-dimensional structures, mainly electron and exciton structures of semiconductor quantum dots.
Teaching assistant of a BSc course on experimental physics.
During my MSc studies, I visited three weeks laboratories of Benito Alen, where I experimentally studied III-V semiconductor quantum dots grown on GaP (samples studied in collaboration with TU Berlin). The extensive optical characterization (steady-state and time-resolved photoluminescence resolved with excitation power, sample temperature, and polarization) shed light on the electronic properties of this unique sample structure, which has been proposed as a building block for QD-flash memories. This experimental work was published in Steindl et al., Phys. Rev. B 100, 195407 (2019) and Steindl et al., New J. Phys. 23, 103029 (2021).
